Company's 1980 and 1988 Long-Term Incentive Plans (the "1980 Plan," the "1988

             See Item 3 for description of Common Stock (including any
             provision of the Company's Articles of Incorporation or Bylaws
             having an effect on a change of control of the Registrant).

             description covering only the series of debentures and Preferred
             Stock being registered hereby.

                              1980 Plan Debentures

             The Company has created a total of twelve series of debentures for
issuance pursuant to debenture options under the 1980 Plan, which have been
designated as the Company's 1982-A Series Convertible Subordinated Debentures
(the "1982-A Series Debentures"), 1982-B Series Convertible Subordinated
Debentures (the "1982-B Series Debentures"), 1982-C Series Convertible
Subordinated Debentures (the "1982-C Series Debentures"), 1982-D Series
Convertible Subordinated Debentures (the "1982-D Series Debentures"), 1983-A
Series Convertible Subordinated Debentures (the "1983-A Series Debentures"),

$50), 1985-A Series, 1986-A Series, 1987-A Series, 1988-A Series and 1989-A
Series Debentures have been created for issuance pursuant to regular debenture
options; the other six series have been created for issuance pursuant to
special debenture options and therefore have certain provisions based on the
provisions initially prescribed in the stock options converted into these
special debenture options.  The Company has authorized the issuance, pursuant

             In certain circumstances described below, the 1980 Plan Debentures
may be redeemed prior to their maturity date.  The twelve debenture series will
be subordinated generally to the Company's other indebtedness, except that they
will rank equally with each other and any other series of debentures created
for issuance under the Plans.  Interest on the 1980 Plan Debentures will be
payable semi-annually on January 1 and July 1 of each year.

             Subject to the conditions described herein, at any time more than
six months after the date of grant of the applicable 1980 Plan Debenture Option
and prior to the redemption or payment thereof, each 1980 Plan Debenture will
be convertible into fully paid and non-assessable shares of the Company's

An amendment to the 1980 Plan, which was approved by the Company's stockholders
in June 1990, authorizes the Board of Directors to determine the appropriate
adjustments, if any, in the conversion prices specified above in the event of
any reclassification, recapitalization, merger, consolidation, reorganization,
issuance of warrants, rights or debentures, stock dividend, stock split or
reverse stock split, cash dividend, property dividend, including, without
limitation, a distribution of the stock of a subsidiary, combination or
exchange of shares, repurchase of shares, or any other change of the Company's
corporate structure, which in the judgment of the Board of Directors,
materially affects the value of the Company's shares.  Any such adjustments to
the conversion prices would be subject to appropriate amendments to the
Indentures under which the Debentures have been issued, and, in order to effect
an appropriate adjustment, to the authorization of additional shares of Series
Stock (defined below) for issuance upon conversion of the Debentures.  Each
share of the Preferred Stock into which the 1980 Plan Debentures are
convertible as described above will be immediately convertible into one share
of Common Stock, subject to adjustment in certain events.  See "Description of
Convertible Preferred Stock."

13, 2004, respectively.  In certain circumstances described below, the 1988
Plan Debentures may be redeemed prior to their due date.  The 1988-1, 1989-1,
1989-2, 1990-1, 1990-2, 1991-1, 1991-2, 1992-1 and 1994-1 Series Debentures
will be subordinated generally to the Company's other indebtedness, except that
they will rank equally with each other and any other series of debentures
created for issuance under the 1988 Plan and all other series of debentures
created for issuance under the 1980 Plan.  Interest on the 1988 Plan Debentures
will be payable semiannually on January 1 and July 1 of each year.

             Subject to the conditions described herein, at any time more than
six months after the date of grant of the applicable 1988 Plan Debenture Option
and prior to the redemption or payment thereof, the 1988-1 Series Debentures
will be convertible at the Conversion Price of $16.125 per share into fully
paid and non-assessable 1988-1 Series Convertible Preferred Stock, the 1989-1
Series Debentures will be convertible at the Conversion Price of $17.50 per
share into fully paid and non-assessable 1989-1 Series Convertible Preferred
Stock, the 1989-2 Series Debentures will be convertible at the Conversion Price
of $13.8125 per share into fully paid and non-assessable 1989-2 Series
Convertible Preferred Stock, the 1990-1 Series Debentures will be convertible
at the Conversion Price of $11.00 per share into fully paid and non- assessable
1990-1 Series Convertible Preferred Stock, the 1990-2 Series Debentures will be
convertible at the Conversion Price of $9.3750 per share into fully paid and
non-assessable 1990-2 Series Convertible Preferred Stock, the 1991-1 Series
Debentures will be convertible at the Conversion Price of $9.8125 per share
into fully paid and non-assessable 1991-1 Series Convertible Preferred Stock,
the 1991-2 Series Debentures will be convertible at the Conversion Price of
$9.3125 per share into fully paid and non-assessable 1991-2 Series Convertible
Preferred Stock, the 1992-1 Series Debentures will be convertible at the
Conversion Price of $7.8125 per share into fully paid and non-assessable 1992-1
Series Convertible Preferred Stock and the 1994-1 Series Debentures will be
convertible at the conversion price of $21.3125 per share into fully paid and
non-assessable 1994-1 Series Convertible Preferred Stock.  An amendment to the
1988 Plan, which was approved by the Company's stockholders in June 1990,
authorizes the Board of Directors to determine the appropriate adjustments, if
any, in the conversion prices specified above in the event of any
reclassification, recapitalization, merger, consolidation, reorganization,
issuance of warrants, rights or debentures, stock dividend, stock split or
reverse stock split, cash dividend, property dividend, including, without
limitation, a distribution of the stock of a subsidiary, combination or
exchange of shares, repurchase of shares, or any other change of the Company's
corporate structure, which in the judgment of the Board of Directors,
materially affects the value of the Company's shares.  Any such adjustments to
the conversion prices would be subject to appropriate amendments to the
Indentures under which the Debentures have been issued, and, in order to effect
an appropriate adjustment, to the authorization of additional shares of Series
Stock for issuance upon conversion of the Debentures.  Each share of the
Preferred Stock will be convertible immediately into one share of Common Stock,
subject to adjustment in certain events.  See "Description of Convertible
Preferred Stock."


             Provisions Applicable to Both the 1980 Plan Debentures
                          and the 1988 Plan Debentures

             The 1980 Plan Debentures and the 1988 Plan Debentures are
hereinafter referred to collectively as the "Debentures."  The following
paragraphs discuss provisions applicable to Debentures issued under either
Plan.  The Debentures will bear interest at a floating rate of 1% less than the
rate





                                      -6-
<PAGE>   8
publicly announced as its prime rate by Deposit Guaranty National Bank in
Jackson, Mississippi, but not more than the maximum legal rate permitted under
the law.  Mississippi usury law permits interest at 15% on Debentures with a
principal amount exceeding $2,500 and 10% on Debentures in smaller amounts.
Also, a provision of the Mississippi law permits interest on Debentures in any
principal amounts at 5% above the Federal Reserve Bank's discount rate (4.75%
at December 30, 1994).  There is no usury limit on Debentures issued between
July 1, 1986 and June 30, 1987 with a principal amount exceeding $125,000.
There is no usury limit on Debentures issued between July 1, 1987 and June 30,
1988 with a principal amount exceeding $75,000.  There is no usury limit on
Debentures issued from and after July 1, 1988 with a principal amount exceeding
$25,000.  The Company expects that the formula interest rate of the Debentures
will remain in compliance with the applicable usury rate, particularly in the
case of Debentures in amounts exceeding $2,500, because of the usury ceilings
applicable to Deposit Guaranty National Bank in establishing its prime rate.
The Company also believes that there is a sound legal basis for not treating
the right to convert the Debentures into Common Stock as constituting
additional interest for purposes of the Mississippi usury law.  Accordingly,
the Company intends to treat the conversion right as not being interest subject
to the Mississippi usury law.

             Amendments to the 1980 and 1988 Plans approved by the stockholders
in November, 1991 changed the six-month holding period before a debenture can
be converted into Preferred Stock so that such holding period now begins on the
date a debenture option is granted, rather than on the date a debenture is
purchased upon exercise of a debenture option.  The Plans were further amended
by the Board of Directors to provide that administrative responsibilities
relating to the Plans be handled by a committee composed of outside directors.
Furthermore, the Company entered into Supplemental Indentures with Deposit
Guaranty National Bank to reflect the change in the debenture holding period
and to require that Preferred Stock issuable upon conversion of a debenture
will not be transferable except in certain situations.  These amendments and
resulting Supplemental Indentures reflect the amended rules, effective May 1,
1991, promulgated by the SEC under Section 16 of the Securities Exchange Act of
1934.

             A participant generally may not sell, assign, transfer, pledge or
otherwise hypothecate a Debenture except by will or intestate succession.  With
the Company's consent, however, participants may pledge Debentures as security
for loans which will provide all or a part of the financing necessary to
purchase the Debentures.  If a participant makes a permitted pledge of a
Debenture, the conversion privilege will not be exercisable during such time as
the Debenture is pledged.  Upon notice from the participant and the lender to
which the Debenture was pledged that the Debenture has been released from the
pledge, the conversion privilege will again be exercisable.  If a participant
sells, assigns, transfers, pledges or otherwise hypothecates a Debenture in a
manner not permitted under the Indenture or if a party forecloses on a
permitted pledge, the conversion right will permanently cease to exist.  Should
the conversion right of a Debenture so terminate, the Company has the option,
but not the obligation, to prepay that Debenture.

             Debentures may be converted in whole or in part but no partial
conversion will be permitted if, following conversion, the remaining principal
amount of the Debenture would be less than $1,000.  Shares of Series Stock will
be issued upon conversion of Debentures in whole shares only.  If more than one
Debenture of the same series is surrendered for conversion at one time by the
same holder, the number of whole shares issuable upon conversion will be
computed upon the basis of the





                                      -7-
<PAGE>   9
aggregate principal amount of such Debentures (or portions thereof specified
for conversion) so surrendered.  Any fractional interest in a share otherwise
deliverable upon conversion will be settled by payment in the form of a check
or cash equal to the product obtained by multiplying the applicable Conversion
Price per share times such fractional interest.

             The Company may redeem the entire series of the 1984-A Series
Debentures or all or any part of the 1982-A, 1982-B, 1982-C, 1982-D, 1983-A,
1984-B, 1985-A, 1986-A, 1987-A, 1988-A, 1989-A, 1989-1, 1990-1, 1991-1 or
1992-1 Series Debentures on any January 1 or July 1 upon mailing a notice of
redemption not less than 12 nor more than 18 months prior to the date fixed for
such redemption to the holders of the Debentures to be redeemed at their last
registered addresses.  Except as provided below, if only a part of the 1982-A,
1982-B, 1982-C, 1982-D, 1983-A, 1984-B, 1985-A, 1986-A, 1987-A, 1988-A, 1989-A,
1989-1, 1990-1, 1991-1 or 1992-1 Series Debentures is to be redeemed, the
Company will specify the amount to be redeemed, and the Trustee will select the
particular Debentures to be redeemed, using a method the Trustee deems fair and
appropriate, which may provide for the selection for redemption of portions of
the principal amount of such Debentures.  If a holder of a 1982-A, 1982-B,
1982-C, 1982-D, 1983-A, 1984-B, 1985-A, 1986-A, 1987-A, 1988-A, 1989-A, 1989-1,
1990-1, 1991-1 or 1992-1 Series Debenture is not employed by an Eligible
Employer, the Company may designate for redemption any of such series of
Debentures owned by such person, regardless of whether the Company redeems any
other of such series of Debentures at the same time.  If the Company calls for
redemption the 1982-A, 1982- B, 1982-C, 1982-D, 1983-A, 1984-B, 1985-A, 1986-A,
1987-A, 1988-A, 1989-A, 1989-1, 1990-1, 1991-1 or 1992-1 Series Debentures
issued pursuant to the 1988 Plan, the Company may also redeem all of the
1988-1, 1989-2, 1990-2, 1991-2, 1992-1 and 1994-1 Series Debentures held by
Outside Directors on any January 1 or July 1 upon mailing a notice of
redemption not less than 12 nor more than 18 months prior to the date fixed for
such redemption to the holders of the 1988 Plan Debentures to be redeemed at
their last registered addresses.  Each Debenture is redeemable for its
principal amount together with accrued interest to the date fixed for
redemption.  Purchasers may convert their Debentures at any time prior to the
close of business on the redemption date, subject to the limitations on
conversion privileges described above.  A holder may redeem a Debenture at its
principal amount plus accrued interest on any January 1 or July 1 more than one
year after issuance of the Debenture.

             In the event that the Company enters into certain merger
transactions, becomes a party to a consolidation, or transfers all or
substantially all of its assets to another company, a supplemental Indenture
will be executed to provide that the holder of each Debenture then outstanding
may convert such Debenture into the kind and amount of shares of stock, cash or
property receivable upon the merger, consolidation, or transfer by a holder of
the number of shares of the applicable series of the Company's Convertible
Preferred Stock issuable upon conversion of such Debenture if such shares of
Preferred Stock had been outstanding immediately prior to such merger,
consolidation or transfer.

             Each Indenture under the 1988 Plan and under the 1980 Plan may be
amended to modify the rights of holders of the respective series of Debentures
covered thereby or otherwise modify the terms of such Indenture with the
consent of the Company, the Trustee and the holders of not less than 66 2/3% in
aggregate principal amount of the respective series of Debentures covered
thereby, except that the maturity date, the rate and time of payment for
interest, the conversion rights and certain other specified terms may not be
modified without the consent of all affected holders of the respective series
of Debentures covered thereby.





                                      -8-
<PAGE>   10
             Each Indenture defines an "Event of Default" as:  (a) any default
in the payment of interest which continues for 30 days after the due date; (b)
any default in the payment of principal when due on the Debentures covered
thereby; (c) failure by the Company to observe or perform any of its other
covenants and agreements in the Debentures covered thereby or in such Indenture
which continues for 60 days after specific written notice of such failure has
been given to the Company by the Trustee or to the Company and the Trustee by
holders of at least 25% in principal amount of the Debentures covered thereby;
(d) certain events of default that cause other indebtedness of the Company to
be accelerated and which are not cured or otherwise remedied within specified
times; and (e) certain events of bankruptcy of the Company.  Upon the happening
and during the continuance of an Event of Default, the Trustee or the holders
of at least 25% in aggregate principal amount of the Debentures covered thereby
may declare the principal and accrued interest on all Debentures covered
thereby to be due and payable immediately.  The holders of a majority in
aggregate principal amount of the outstanding Debentures of the series so
affected will have the right to direct the time, method and place of conducting
any proceeding or any remedy available to the Trustee, or exercising any trust
or power conferred on the Trustee, but the Trustee, subject to its obligation
to exercise such of the rights and powers vested in it by each Indenture and to
use the same degree of care and skill in their exercise or use as a prudent man
would exercise or use under the circumstances in the conduct of his own
affairs, may decline to follow any such direction if the Trustee in good faith
determines that the proceedings so directed would involve it in a personal
liability or be in conflict with any law or provision of such Indenture.  The
Company is required by each Indenture to deliver annually to the Trustee a
certificate from appropriate officers certifying that, to the best of their
knowledge, the Company has satisfied all of its obligations under such
Indenture during the preceding fiscal year.

             In the event of any insolvency or bankruptcy proceedings, and any
receivership, liquidation, reorganization, or other similar proceedings in
connection therewith, relative to the Company or to its creditors, as such, or
to its property, and in the event of any proceedings for voluntary liquidation,
dissolution, or other winding up of the Company, whether or not involving
insolvency or bankruptcy, or in the event that any Debenture is declared due
and payable before its expressed maturity for any reason, then the holders of
Senior Indebtedness (as defined below) then outstanding shall be entitled to
receive payment in full of all such Senior Indebtedness before the holders of
the Debentures are entitled to receive any payment on account of principal or
interest upon the Debentures.

             No payment of principal or interest will be made on the Debentures
during any period that any Senior Indebtedness has matured and has not been
paid in full, refunded or replaced by new indebtedness.

             Senior Indebtedness is defined in each Indenture as the principal
and unpaid interest on (a) indebtedness for money borrowed (other than the
Debentures) for the payment of which the Company is responsible or liable,
whether outstanding on the date of execution of such Indenture or thereafter
created, incurred, assumed, or guaranteed, unless in the instrument creating or
evidencing the same or pursuant to which the same is created provides that such
indebtedness is not superior in right of payment to the Debentures, and (b)
renewals, extensions, and deferrals of any such indebtedness.  The Indentures
do not contain any limitations on the amount of Senior Indebtedness which may
be hereafter incurred by the Company.  At June 30, 1994, the Company had
outstanding





                                      -9-
<PAGE>   11
or guaranteed approximately $103,480,000 of indebtedness which would constitute
Senior Indebtedness under the Indentures.

             By reason of such subordination, in the event of the Company's
insolvency, certain general creditors of the Company may recover more ratably
than holders of the Debentures.

                   DESCRIPTION OF CONVERTIBLE PREFERRED STOCK

             The Company is authorized to issue up to 20,000,000 shares of
Preferred Stock in one or more series (the "Preferred Stock"), and the Board is
authorized to determine the form, class, series and amounts in which the
Preferred Stock shall be issued; the price or prices (not less than par) at
which such stock shall be sold; the dividend rights, conversion rates,
conversion prices, par value, voting privileges, redemption prices, maturity
dates, and any other terms and conditions relative to the issuance of the
Preferred Stock.  Pursuant to this authority, the Board has established the
1982-A, 1982-B, 1982-C, 1982-D, 1983-A, 1984-A, 1984-B, 1985-A, 1986-A, 1987-A,

shares of the 1992-1 Series and 1,000 shares of the 1994-1 Series upon
conversion of, respectively, the 1982-A, 1982-B, 1982-C, 1982-D, 1983-A,
1984-A, 1984-B, 1985-A, 1986-A, 1987-A, 1988-A, 1988-1, 1989-A, 1989-1, 1989-2,
1990-1, 1990-2, 1991-1, 1991-2, 1992-1 and 1994- 1 Series Debentures.

             The 1982-A, 1982-B, 1982-C, 1982-D, 1983-A, 1984-A, 1984-B,
1985-A, 1986-A, 1987-A, 1988-A, 1988-1, 1989-A, 1989-1, 1989-2, 1990-1, 1990-2,
1991-1, 1991-2, 1992-1 Series and 1994-1 Series Convertible Preferred Stock
(sometimes referred to collectively as the "Series Stock") each has a par value
of $1.00 per share and is entitled to a quarterly non-cumulative preferential
dividend of $.05 per share, payable quarterly.  Each share of Series Stock will
be convertible immediately into one share of the Company's Common Stock,
subject to adjustment in certain events.  Amendments to the Plans adopted by
the Company's stockholders in June 1990 authorized the Board of Directors to
determine the appropriate adjustments, if any, to the number of shares of the
Company's Common Stock issuable upon conversion of the Series Stock in the
event of a reclassification, recapitalization, merger, consolidation,
reorganization, issuance of warrants, rights or debentures, stock dividend,
stock split or reverse stock split, cash dividend, property dividend,
including, without limitation, a distribution of the stock of a subsidiary,
combination or exchange of shares, repurchase of shares, or any other change of
the Company's corporate structure, which, in the judgment of the Board of
Directors materially affects the value of the Company's shares subsequent to
the grant of a regular debenture option or subsequent to the conversion of a
stock option into a special debenture option.

             The Company will not issue fractional shares of Common Stock upon
conversion of Series Stock.  In lieu of such fractions, the Company will pay to
the holder of Series Stock requesting conversion an amount in cash equal to the
market value of such fraction at the time of such conversion, as determined by
the Board.

             Any or all of the Series Stock outstanding at any time may be
redeemed at the option of the Company in whole or in part at any time upon not
less than 20 nor more than 60 days notice to the record holders at their last
addresses as shown in the stock transfer records of the Company.  The
conversion right with respect to any shares called for redemption will be lost
unless exercised no later than the day fixed for redemption.  The redemption
price per share (the "Redemption Price") for Series Stock will be as follows
(plus in each case accrued and unpaid dividends per share on the respective
series of stock to the date of redemption):

Under the Mississippi Business Corporation Act, no redemption could be made if
the Company were insolvent or would be rendered insolvent by such redemption or
if such redemption would reduce the Company's net assets below the aggregate
amount payable to holders of shares having prior or equal rights to the
Company's assets upon involuntary dissolution.

             Upon any voluntary or involuntary liquidation or dissolution of
the Company, the holders of the Series Stock will be entitled to a liquidation
preference equal to the Redemption Price for the





                                      -11-
<PAGE>   13
appropriate series as set forth above, plus any declared but unpaid dividends
on the respective series of stock, before any distribution of assets may be
made to the holders of Common Stock or other shares junior to the Series Stock.
After the holders of the Series Stock have received such amount, they may not
participate in any remaining assets and surplus funds of the Company.  If the
amounts which holders of the Series Stock and any other series of Preferred
Stock ranking equally as to distribution of assets are entitled to receive in
any voluntary or involuntary liquidation or dissolution are not paid in full,
the shares of Series Stock and such other series of Preferred Stock will share
ratably in any distribution of assets in accordance with the amounts which
would be payable on such distribution if all amounts to which the holders of
each such series are entitled are paid in full.

             Additional series of Preferred Stock may be created and shares
thereof may be issued by the Company without any approval or action by the
holders of the Series Stock being necessary, and such additional series of
stock may rank equally with the Series Stock as to distribution of the
Company's assets in the event of liquidation or dissolution.

             The holders of shares of Series Stock will not be entitled to vote
except in certain circumstances as provided by the Mississippi Business
Corporation Act.  Holders of Series Stock do not have preemptive rights.


ITEM 5.  Interests of Named Experts and Counsel

             Legal matters, other than those relating to tax consequences, in
connection with the securities covered by this Prospectus have been passed upon
by J. Steve Chustz, General Counsel of the Company.  Mr. Chustz also serves as
General Counsel for various subsidiaries of the Company.  As of January 30,
1995, Mr. Chustz beneficially owned 1,227 shares of the Company's Common Stock
and 23,500 shares of the Company's Common Stock through the right to exercise
Non- Qualified Stock Options.

             The consolidated financial statements and financial statement
schedules of the Company and subsidiaries as of June 30, 1994 and 1993 and for
each of the years in the three-year period ended June 30, 1994, which are
incorporated herein by reference, have been incorporated herein in reliance
upon the reports, also incorporated herein by reference, of KPMG Peat Marwick
LLP, independent certified public accountants, and upon the authority of said
firm as experts in accounting and auditing.  To the extent that KPMG Peat
Marwick LLP audits and reports on financial statements of the Company and
subsidiaries issued at future dates, and consents to the use of their reports
thereon, such financial statements also will be incorporated herein by
reference in reliance upon their reports and said authority.


ITEM 6.  Indemnification of Directors and Officers

             As permitted by Mississippi law, the stockholders of the Company,
at the Annual Meeting of Stockholders on November 7, 1985, adopted a resolution
providing for indemnification of officers, directors and employees.  The 1985
resolution, which replaced a similar resolution adopted in 1970, generally
clarifies and broadens the circumstances under which indemnity is provided by
the





                                      -12-
<PAGE>   14
Company, and extends indemnification beyond directors and officers, to
employees.  It specifies standards of conduct required to be met to qualify for
indemnity and establishes procedures for determining whether these standards
are met.  These standards require that the person to be indemnified either:
(a) be wholly successful, on the merits or otherwise, in any action or
proceeding against such person or (b) otherwise establish that such person
acted in good faith and in a manner such person reasonably believed to be in,
or not opposed to, the best interests of the Company, and in the case of any
criminal action or proceeding, had no reasonable cause to believe that the
conduct was unlawful.  Whether these standards are met will be determined by
those directors or shareholders not involved in the matter at issue or by
special legal counsel selected by the directors.  In the case of any action or
suit by or in the right of the Company, any person finally adjudged liable for
gross negligence or willful misconduct in performing duties for the Company
will not be entitled to indemnification unless a court determines that
indemnification is proper under the circumstances.  Advancement of expenses
will be allowed upon receipt of an undertaking to repay should it ultimately be
determined that an individual is not entitled to indemnity.

             The Company maintains officers and directors liability insurance
against certain claims arising out of such persons' services to the Company.
The Company has entered into Indemnification Agreements with certain of its
officers and directors.  These Indemnification Agreements provide for
indemnification of such officers or directors in the circumstances and subject
to the conditions set forth in the Company's 1985 resolution.  The effect of
the Indemnification Agreements is to add to the indemnification rights granted
by the 1985 resolution as currently in effect a contractual right to such
indemnification which cannot be terminated or altered by amendment of the 1985
resolution.

ITEM 9.  Undertakings

(a) The undersigned Registrant hereby undertakes:

    (1)      To file, during any period in which offers or sales are being
             made, a post-effective amendment to this registration statement:

                  (i)        To include any prospectus required by Section
                             10(a)(3) of the Securities Act of 1933;

                 (ii)        To reflect in the prospectus any facts or events
                             arising after the effective date of the
                             registration statement (or the most recent
                             post-effective amendment thereof) which,
                             individually or in the aggregate, represent a
                             fundamental change in the information set forth in
                             the registration statement;

                (iii)        To include any material information with respect
                             to the plan of distribution not previously
                             disclosed in the registration statement or any
                             material change to such information in the
                             registration statement;

             Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not
             apply if the registration statement is on Form S-3, Form S-8 or
             Form F3 and the information required to be included in a
             post-effective amendment by those paragraphs is contained in
             periodic reports filed with or furnished to the Commission by the
             Registrant pursuant to Section 13 or Section 15(d) of the
             Securities Exchange Act of 1934 that are incorporated by reference
             in the registration statement.

    (2)      That, for the purpose of determining any liability under the
             Securities Act of 1933, each such post-effective amendment shall
             be deemed to be a new registration statement relating to the
             securities offered therein, and the offering of such securities at
             that time shall be deemed to be the initial bona fide offering
             thereof.





                                      -14-
<PAGE>   16
    (3)      To remove from registration by means of a post-effective amendment
             any of the securities being registered which remain unsold at the
             termination of the offering.

(b) The undersigned Registrant hereby undertakes that, for purposes of
    determining any liability under the Securities Act of 1933, each filing of
    the Registrant's annual report pursuant to Section 13(a) or Section 15(d)
    of the Securities Exchange Act of 1934 (and, where applicable, each filing
    of an employee benefit plan's annual report pursuant to Section 15(d) of
    the Securities Exchange Act of 1934) that is incorporated by reference in
    the registration statement shall be deemed to be a new registration
    statement relating to the securities offered therein, and the offering of
    such securities at that time shall be deemed to be the initial bona fide
    offering thereof.

(h) Insofar as indemnification for liabilities arising under the Securities Act
    of 1933 may be permitted to directors, officers and controlling persons of
    the Registrant pursuant to the foregoing provisions, or otherwise, the
    Registrant has been advised that in the opinion of the Securities and
    Exchange Commission such indemnification is against public policy as
    expressed in the Act and is, therefore, unenforceable.  In the event that
    a claim for indemnification against such liabilities (other than the
    payment by the Registrant of expenses incurred or paid by a director,
    officer or controlling person of the Registrant in the successful defense
    of any action, suit or proceeding) is asserted by such director, officer or
    controlling person in connection with the securities being registered, the
    Registrant will, unless in the opinion of its counsel the matter has been
    settled by controlling precedent, submit to a court of appropriate
    jurisdiction the question whether such indemnification by it is against
    public policy as expressed in the Act and will be governed by the final
    adjudication of such issue.

                 certain debenture options automatically granted November 14,
                 1994, and further desires to determine and fix the rights,
                 preferences and other terms and conditions relating to such
                 series and the number of shares constituting such series;

                          NOW, THEREFORE, BE IT RESOLVED, that the Board of
                 Directors hereby establishes a series of preferred stock of
                 the Corporation to be designated 1994-1 Series Convertible
                 Preferred Stock, which shall be available for issuance solely
                 upon conversion of the Corporation's 1994-1 Series Convertible
                 Subordinated Debentures, which, in turn, will be available for
                 issuance in accordance with and upon exercise of certain
                 options, all of which shall be granted on the same date
                 pursuant to the Corporation's 1988 Long-Term Incentive Plan,
                 entitling the holders thereof to purchase such series of
                 debentures (such date being referred to as the "Original Grant
                 Date");

                          BE IT FURTHER RESOLVED, that the 1994-1 Series
                 Convertible Preferred Stock shall consist of 11,000 shares;

                          BE IT FURTHER RESOLVED, that the rights, preferences
                 and other terms and conditions of the 1994-1 Series
                 Convertible Preferred Stock shall be as follows:

                 1.       PAR VALUE.  The par value for the 1994-1 Series
                 Convertible Preferred Stock shall be $1.00 per share.

                 2.       DIVIDENDS.  The holders of record of 1994-1 Series
                 Convertible Preferred Stock shall be entitled to receive, out
                 of funds
<PAGE>   3
                 legally available therefor, cash dividends at the rate of $.05
                 per share per quarter.  All dividends payable hereunder shall
                 be payable quarterly or otherwise as the Board of Directors
                 may from time to time determine when and as declared by the
                 Board of Directors.  The right to such dividends on 1994-1
                 Series Convertible Preferred Stock shall not be cumulative and
                 no right shall accrue to the holders of such shares by reason
                 of the fact that dividends on such shares are not declared in
                 any prior year.  The holders of 1994-1 Series Convertible
                 Preferred Stock shall be entitled to no other cash dividends
                 in excess of the dividends at said rate.

                 3.       REDEMPTION.  The 1994-1 Series Convertible Preferred
                 Stock may be redeemed, in whole or in part, at the option of
                 the Corporation by vote of its Board of Directors, at any time
                 or from time to time, at a redemption price per share equal to
                 the "Purchase Price," as defined below, plus an amount equal
                 to all dividends declared but unpaid at the dated fixed for
                 redemption, and such price, plus such dividends, is
                 hereinafter referred to as the "Redemption Price."  The
                 Purchase Price per share shall be the market value, as
                 determined by the Board of Directors, of one share of the
                 Corporation's Common Stock on the Original Grant Date.

                 In case of the redemption of only a part of the outstanding
                 1994-1 Series Convertible Preferred Stock, this Corporation
                 shall designate by lot the shares to be redeemed or shall
                 effect such redemption pro rata.

                 Not more than 60 days, but at least 20 days prior to the date
                 fixed for redemption, a written notice shall be mailed to each
                 holder of record of 1994-1 Series Convertible Preferred Stock
                 whose shares are to be redeemed, by certified mail with
                 postage prepaid, addressed to each such holder at his address
                 as shown on the records of the Corporation (a) notifying each
                 holder of the election of the Corporation to redeem such
                 shares, (b) stating the date fixed for redemption thereof, (c)
                 setting forth the Redemption Price, and (d) stating the place
                 at which each such holder may obtain payment
<PAGE>   4
                 of the Redemption Price upon surrender of his share
                 certificates.

                 On or after the date fixed in such notice of redemption, each
                 holder of 1994-1 Series Convertible Preferred Stock to be
                 redeemed shall present and surrender his certificate or
                 certificates representing such stock to this Corporation at a
                 place designated in such notice and thereupon the Redemption
                 Price of such shares shall be paid to or on the order of the
                 person whose name appears on such certificate or certificates
                 as the owner thereof and each surrendered certificate shall be
                 canceled.  In case less than all of the shares represented by
                 any such certificate are redeemed, a new certificate shall be
                 issued representing the unredeemed shares.  From and after the
                 date fixed in any such notice as the date of redemption,
                 unless default is made in the payment of the Redemption Price,
                 all rights of the holders thereof as shareholders of the
                 Corporation, except the right to receive the Redemption Price,
                 shall cease and determine, and such shares shall not
                 there-after be transferred on the books of the Corporation,
                 and such stock shall not be deemed to be outstanding for any
                 purpose whatsoever.

                 The Corporation may at its option at any time after such
                 notice of redemption has been given, deposit a sum sufficient
                 to redeem, on the date fixed for redemption, the shares of
                 1994-1 Series Convertible Preferred Stock called for
                 redemption and not yet redeemed with a bank or trust company
                 in Mississippi, as a trust fund for the benefit of the
                 respective holders of the shares designated for redemption,
                 and such deposit, from and after the date fixed for
                 redemption, shall constitute full payment of the Redemption
                 Price of the shares to the holders thereof and shall be
                 conclusive evidence that no default shall be made in the
                 payment of the Redemption Price as to such shares.

                 Shares of the 1994-1 Series Convertible Preferred Stock
                 redeemed by the Corporation shall not thereafter be disposed
                 of as shares of such Series, but upon acceptance by the
                 Secretary of State of Mississippi for filing of a statement of
                 cancellation relating to the redeemed shares, such shares
                 shall become
<PAGE>   5
                 authorized and unissued shares of Preferred Stock which may be
                 designated as shares of any other series.

                 4.       LIQUIDATION PREFERENCE.  In the event of any
                 voluntary or involuntary dissolution, liquidation or winding
                 up of the Corporation, the holders of shares of 1994-1 Series
                 Convertible Preferred Stock outstanding shall be entitled to
                 receive, or to have deposited in trust for them as provided in
                 Section 3 here-of, out of assets of the Corporation, before
                 any distribution of any assets shall be made to the holders of
                 Common Stock or other shares junior to the 1994-1 Series
                 Convertible Preferred Stock as to distribution of assets, an
                 amount which shall be equal to the Purchase Price, as defined
                 above, for such shares plus declared but unpaid dividends
                 thereon.  After the holders of 1994-1 Series Convertible
                 Preferred Stock shall have received such amount, they shall
                 not participate in any remaining assets and surplus funds of
                 the Corporation.

                 If the amounts which each of the holders of the shares of the
                 1994-1 Series Convertible Preferred Stock, and any other
                 series of Preferred Stock of the Corporation ranking equally
                 as to distribution of assets with the shares of 1994-1 Series
                 Convertible Preferred Stock, are entitled to receive in such
                 events are not paid, or deposited in trust, in full, the
                 shares of 1994-1 Series Convertible Preferred Stock and of
                 such other series shall share ratably in any distribution of
                 assets in accordance with the amounts which would be payable
                 on such distribution if all amounts to which the holders of
                 the 1994-1 Series Convertible Preferred Stock and of each such
                 series are entitled were paid, or deposited in trust, in full.

                 Neither the merger of the Corporation with or into any other
                 Corporation nor the sale of all or substantially all of its
                 assets shall be deemed a dissolution, liquidation or winding
                 up of the Corporation within the meaning of this Section.

                 5.       CONVERSION RIGHTS.  The holders of shares of 1994-1
                 Series Convertible Preferred Stock shall have conversion
                 rights as follows:
<PAGE>   6
                          (a)     The shares of 1994-1 Series Convertible
                 Preferred Stock shall be convertible, at the option of the
                 respective holders thereto, at the office of the Corporation
                 into fully paid and nonassessable shares of Common Stock of
                 the Corporation, as follows:

                                  (i)      The number of shares of Common Stock
                 into which a share of 1994-1 Series Convertible Preferred
                 Stock is to be converted shall be determined by multiplying
                 one share times the "Conversion Multiplier," as described
                 below.  On the "Original Grant Date," as defined above, the
                 Conversion Multiplier shall be one, and unless and until the
                 Conversion Multiplier is adjusted as provided below, each
                 share of 1994-1 Series Convertible Preferred Stock shall be
                 convertible into one share of Common Stock.

                                  (ii)     If the Corporation shall at any time
                 after the Original Grant Date effect a subdivision of the
                 outstanding Common Stock, the Conversion Multiplier then in
                 effect immediately before such subdivision shall be
                 proportionately increased, and conversely, if the Corporation
                 shall at any time after the Original Grant Date combine the
                 outstanding shares of Common Stock, the Conversion Multiplier
                 then in effect immediately before such combination shall be
                 proportionately decreased.  Any adjustment hereunder shall
                 become effective at the close of business on the date the
                 subdivision or combination becomes effective.

                                  (iii)    If the Corporation shall at any time
                 after the Original Grant Date make or issue, without payment
                 of consideration, a dividend or other distribution payable in
                 additional shares of Common Stock, the Conversion Multiplier
                 then in effect shall be increased as of the close of business
                 on the record date for the determination of holders entitled
                 thereto or the date on which the stock transfer books of the
                 Corporation are closed with respect thereto, or, if no such
                 record date has been fixed and the stock transfer books are
                 not so closed, the date of such making or issuance, by
                 multiplying the Conversion Multiplier then in effect by a
                 fraction:
<PAGE>   7
                                        (A)     the numerator of which shall be
                 the total number of shares of Common Stock issued and
                 outstanding immediately prior to such date, plus the number of
                 shares of Common Stock issuable in payment of such dividend or
                 distribution; and

                                        (B)     the denominator of which shall
                 be the total number of shares of Common Stock issued and
                 outstanding immediately prior to such date;

                 Provided, however, that if such record date shall have been
                 fixed or if the stock transfer books are so closed and such
                 dividend is not fully paid or if such distribution is not
                 fully made on the date therefor, the Conversion Multiplier
                 shall be recomputed accordingly as of the close of business on
                 such date of alteration.

                                  (iv)     If the Corporation shall at any time
                 after the Original Grant Date make or issue, without payment
                 of consideration, a dividend or other distribution payable to
                 holders of Common Stock in securities or other assets of the
                 Corporation (other than cash or shares of Common Stock),
                 provisions shall be made so that the holders of the 1994-1
                 Series Convertible Preferred Stock shall receive upon the
                 conversion thereof in addition to the number of shares of
                 Common Stock receivable thereupon, the amount of securities or
                 other assets of the Corporation that they would have received
                 had their 1994-1 Series Convertible Preferred Stock been
                 converted into Common Stock on the date of such event and had
                 they thereafter, during the period from the date of such event
                 to and including the conversion date, retained such securities
                 or other assets receivable by them as aforesaid during such
                 period, giving application to all adjustments called for
                 during such period under this Section 5 with respect to the
                 rights of the holders of the 1994-1 Series Convertible
                 Preferred Stock.

                                  (v)      In case of any capital
                 reorganization or any reclassification of the capital stock of
                 the Corporation or in case of the consolidation or merger of
                 the Corporation with or into another corporation or the
                 conveyance of all or substantially all of the assets of the
                 Corporation to another
<PAGE>   8
                 corporation, each share of 1994-1 Series Convertible Preferred
                 Stock shall thereafter be convertible into the number of
                 shares of stock or other securities or property to which a
                 holder of the number of shares of Common Stock of the
                 Corporation deliverable upon conversion of such shares of
                 1994-1 Series Convertible Preferred Stock would have been
                 entitled upon such reorganization, reclassification,
                 consolidation, merger or conveyance; and in any such case,
                 appropriate adjustment (as determined in good faith by the
                 Board of Directors) shall be made in the application of the
                 provisions herein set forth with respect to the rights and
                 interests thereafter of the holders of the shares of 1994-1
                 Series Convertible Preferred Stock, to the end that the
                 provisions set forth herein shall thereafter be applicable, as
                 nearly as reasonably may be, in relation to any shares of
                 stock or other property thereafter deliverable upon the
                 conversion of the shares of 1994-1 Series Convertible
                 Preferred Stock.

                                  (vi)     In each case of an adjustment of the
                 Conversion Multiplier or the number of shares of Common Stock
                 or other securities issuable upon conversion of the 1994-1
                 Series Convertible Preferred Stock, the Corporation shall
                 compute such adjustment in accordance herewith and prepare a
                 certificate showing such adjustment, and shall, upon request,
                 provide a copy of such certificate to each registered holder
                 of the 1994-1 Series Convertible Preferred Stock.  The
                 certificate shall set forth such adjustment, showing in detail
                 the facts upon which such adjustment is based, including a
                 statement of (A) the Conversion Multiplier at the time in
                 effect for the 1994-1 Series Convertible Preferred Stock, and
                 (B) the number, type and amount, if any, of other property
                 that at the time would be received upon conversion of the
                 1994- 1 Series Convertible Preferred Stock.

                          (b)     Before any holder of 1994-1 Series
                 Convertible Preferred Stock shall be entitled to convert the
                 same into shares of Common Stock, he shall surrender the
                 certificate or certificates therefor, duly endorsed, at the
                 office of the Corporation and shall give written notice to the
                 Corporation that he elects to convert the same and shall state
                 in
<PAGE>   9
                 writing therein the name or names in which he wishes the
                 certificate or certificates for shares of Common Stock to be
                 issued.  If the holder fails to specify the name in which
                 certificates are to be issued, they shall be issued in his
                 name.  The Corporation, as soon as practicable thereafter,
                 shall issue and deliver at such office to such holder of
                 1994-1 Series Convertible Preferred Stock, or to his nominee
                 or nominees, certificates for the number of full shares of
                 Common Stock to which he shall be entitled as aforesaid,
                 together with cash in lieu of any fraction of a share as
                 hereinafter provided.  Such conversion shall be deemed to have
                 been made as of the date of such surrender of the shares of
                 1994-1 Series Convertible Preferred Stock to be converted (or,
                 in the event of a proposed redemption and if the Corporation
                 so allows, on the date of receipt of satisfactory notice of
                 conversion if certificates of 1994-1 Series Convertible
                 Preferred Stock so converted are thereafter delivered to the
                 Corporation within 30 days), and the person or persons
                 entitled to receive the shares of Common Stock issuable upon
                 such conversion shall be treated for all purposes as the
                 record holder or holders of such shares of Common Stock on
                 said date.

                          (c)     In case:

                                  (i)      the Corporation shall take a record
                 of the holders of shares of its Common Stock for the purpose
                 of entitling them to receive a dividend, or any other
                 distribution, other than ordinary cash dividends; or

                                  (ii)     the Corporation shall take a record
                 of the holders of shares of its Common Stock for the purpose
                 of entitling them to subscribe for or purchase any shares of
                 stock of any class or to receive any other rights; or

                                  (iii)    of any capital reorganization of the
                 Corporation, reclassification of the capital stock of the
                 Corporation (other than a subdivision or combination of its
                 outstanding shares of Common Stock), consolidation or merger
                 of the Corporation with or into another corporation, or
                 conveyance of all or substantially all of
<PAGE>   10
                 the assets of the Corporation into another corporation; or

                                  (iv)     of the voluntary or involuntary
                 dissolution, liquidation or winding up of the Corporation,

                 then the Corporation shall cause to be mailed to the holders
                 of record of 1994-1 Series Convertible Preferred Stock or any
                 security convertible into 1994-1 Series Convertible Preferred
                 Stock at their last addresses as they shall appear on the
                 records of the Corporation, at least 20 days (or 10 days in
                 any case specified in clauses (1) and (2) above) prior to the
                 applicable record date hereinafter specified, a notice stating
                 (1) the date on which a record is to be taken for the purpose
                 of such dividend or distribution of rights, or, if a record is
                 not to be taken, the date as of which the holders of Common
                 Stock of record would be entitled to such dividend or
                 distribution of rights, or (2) the date on which such capital
                 reorganization, reclassification, consolidation, merger, sale,
                 dissolution, liquidation or winding up is expected to become
                 effective, and the date as of which it is expected that the
                 holders of Common Stock of record shall be entitled to
                 exchange their shares of Common Stock for securities or other
                 assets deliverable upon such reorganization, reclassification,
                 consolidation, merger, sale, dissolution, liquidation or
                 winding up.

                          (d)     The Corporation will at all times reserve and
                 keep available out of its authorized Common Stock and/or
                 shares of its Common Stock then owned or held by or for the
                 account of the Corporation, solely for the purpose of delivery
                 upon conversion of 1994-1 Series Convertible Preferred Stock,
                 such number of shares of Common Stock as shall then be
                 deliverable upon the conversion of all outstanding or
                 potentially issuable 1994-1 Series Convertible Preferred
                 Stock.  All shares of Common Stock which shall be so
                 deliverable shall be duly and validly issued and fully paid
                 and nonassessable.

                          (e)     If any shares of Common Stock required to be
                 reserved for purposes of conversion of 1994-1 Series
                 Convertible Preferred Stock require registration with or
<PAGE>   11
                 approval of any governmental authority under any federal or
                 state law, or listing upon any national securities exchange,
                 before such shares may be issued upon conversion, the
                 Corporation will in good faith and as expeditiously as
                 possible endeavor to cause such shares to be duly registered,
                 approved or listed, as the case may be.

                          (f)     The Corporation will pay any and all issue
                 and other taxes that may be payable in respect of any issue or
                 delivery of shares of Common Stock on conversion of shares of
                 1994-1 Series Convertible Preferred Stock pursuant hereto.
                 The Corporation shall not, however, be required to pay any tax
                 which may be payable in respect of any transfer involved in
                 the issue and delivery of shares of Common Stock in a name
                 other than that in which the shares of 1994-1 Series
                 Convertible Preferred Stock so converted were registered, and
                 no such issue or delivery shall be made unless and until the
                 person requesting such issue has paid to the Corporation the
                 amount of any such tax, or has established, to the
                 satisfaction of the Corporation, that such tax has been paid.

                          (g)     No fractional shares of Common Stock shall be

                         FIRST MISSISSIPPI CORPORATION
                           1994-1 SERIES CONVERTIBLE
                             SUBORDINATED DEBENTURE

                 This Debenture is one of a duly authorized issue of Debentures
of the Company, designated as its 1994-1 Series Convertible Subordinated
Debentures (herein referred to as the "Debentures"), limited to the aggregate
principal amount of $21,312.50 all issued and to be issued under and pursuant
to an Indenture dated as of November 14, 1994 (herein referred to as the
"Indenture"), duly executed and delivered by the Company to Deposit Guaranty
National Bank (herein referred to as the "Trustee," which term includes any
Successor Trustee under the Indenture), to which Indenture and all indentures
supplemental hereto reference is hereby made for a description of the
respective rights thereunder of the Trustee, the Company and the holders of the
Debentures.

                 The indebtedness evidenced by the Debentures is, to the extent
provided in the Indenture, subordinate and junior to the prior payment in full
of the principal of and interest on all Senior Indebtedness, as defined in the
Indenture, and this Debenture is issued subject to the provisions of the
Indenture with respect thereto.  Each holder of this Debenture, by accepting
the same, agrees to be bound by such provisions of the Indenture and authorizes
and directs the Trustee to take such action on his behalf as may be necessary
or appropriate to acknowledge or effectuate the subordination of this Debenture
as provided in the Indenture and appoints the Trustee his attorney-in-fact for
any and all such purposes.  Each holder of this Debenture, by accepting the
same, agrees that each holder of Senior Indebtedness, whether created or
acquired before or after the issuance of the Debentures, shall be deemed
conclusively to have relied on such provisions in acquiring and continuing to
hold, or in continuing to hold, such Senior Indebtedness.

                 Subject to the provisions of the Indenture, at the option of
the holder hereof, this Debenture or any portion hereof may, at any time more
than six months after the date of the award of the debenture option pursuant to
which the Debenture was purchased and at or before the close of business on the
Due Date referred to on the face hereof, be converted at the principal amount
hereof, or of such portion hereof, into fully paid and nonassessable shares of
the Company's Series 1994-1 Convertible Preferred Stock (the "1994-1 Series
Stock") at the Conversion Price per share set forth on the face hereof upon
surrender of this Debenture to the Company at its office or agency in Jackson,
Mississippi, accompanied by written notice of election to convert and, if so
required by the Company, instruments of transfer in form satisfactory to the
Company, duly executed by the registered





                                       4
<PAGE>   12
holder or by his duly authorized attorney.   Fractional shares of 1992-1 Series
Stock will not be issued upon any conversion, but an amount equal to the value
of such fractional interest at the conversion price per share, will be paid in
cash to the registered holder.  Accrued interest on this Debenture through the
day immediately preceding the date of conversion will be paid as provided in
the Indenture.

                 The Debentures may not be prepaid by the Company prior to the
Due Date except as provided in Sections 3.01, 3.02, and 3.04 of the Indenture
or at the election of the holder as provided in Section 3.05 of the Indenture.

                 The Debentures are issuable as registered Debentures without
coupons in denominations approved by the Company, such approval to be evidenced
by the execution thereof.  In the manner and subject to the limitations
provided in the Indenture, Debentures are exchangeable, without charge except
for any tax or other governmental charge imposed in connection therewith, for
other Debentures of any other authorized denomination or denominations of an
equal aggregate principal amount at the office or agency of the Company
referred to on the face hereof.

                 The Company, the Trustee, any paying agent, any conversion
agent and any Debenture registrar may deem and treat the registered holder
hereof as the absolute owner hereof (whether or not this Debenture shall be
overdue and notwithstanding any notation of ownership or other writing hereon
by anyone other than the Company or any Debenture registrar), for the purpose
of receiving payment of or on account of the principal hereof, and interest
hereon, for the conversion hereof and for all other purposes, and neither the
Company nor the Trustee nor any paying agent, conversion agent or Debenture
registrar shall be affected by any notice to the contrary.

                 In case an Event of Default, as defined in the Indenture,
shall have occurred and be continuing, the principal hereof may be declared,
and upon such declaration shall become, due and payable, in the manner, with
the effect and subject to the conditions provided in the Indenture.  The
Indenture provides that in certain events such declaration and its consequences
may be waived by the holders of a majority in aggregate principal amount of the
Debentures then outstanding.

                 It is also provided in the Indenture that, prior to any
declaration accelerating the maturity of the Debentures as the result of an
Event of Default, the holders of a majority in aggregate principal amount of
the Debentures at the time outstanding may on behalf of the holders of all of
the Debentures waive any past default under the Indenture and its consequences
except a default in the payment of the principal of or interest on any of the
Debentures.  Any such consent or waiver by the holder





                                       5
<PAGE>   13
of this Debenture (unless revoked as provided in the Indenture) shall be
conclusive and binding upon such holder and upon all future holders and owners
of this Debenture and any Debentures which may be issued in exchange or
substitution herefor, irrespective of whether or not any notation thereof is
made upon this Debenture or such other Debentures.

                 The Indenture contains provisions permitting the Company and
the Trustee, with the consent of the holders of not less that 66-2/3% in
aggregate principal amount of the Debentures at the time outstanding, evidenced
as in the Indenture provided, to execute supplemental indentures adding any
provisions to or changing in any manner or eliminating any of the provisions of
the Indenture or of any supplemental indenture or modifying in any manner the
rights of the holders of the Debentures; provided, however, that no such
supplemental indenture shall (i) extend the fixed maturity of any Debentures,
or reduce the rate or extend the time of payment of interest thereon, or reduce
the principal amount thereof, or modify the provisions of the Indenture with
respect to the subordination of the Debentures, or impair the right to convert
the Debentures into 1994-1 Series Stock on the terms set forth in the
Indenture, or change any place of payment where or the coin or currency in
which any payment may be made, without the consent of the holder of each
Debenture so affected, or (ii) reduce the aforesaid percentage of Debentures,
the holders of which are required to consent to any such supplemental
indenture, without the consent of the holders of all Debentures then
outstanding.

                 No reference herein to the Indenture and no provision of this
Debenture or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay the principal of and
interest on this Debenture at the time and place and at the rate and in the
currency herein prescribed.

                 No recourse for the payment of the principal of or interest on
this Debenture, or for any claim based hereon or otherwise in respect hereof,
and no recourse under or upon any obligation, covenant or agreement of the
Company in the Indenture or any indenture supplemental thereto or in any
Debenture, or because of the creation of any indebtedness represented thereby,
shall be had against any stockholder, officer or director, as such, past,
present or future, of the Company or of any successor corporation, either
directly or through the Company or any successor corporation, whether by virtue
of any constitution, statute or rule of law or by the enforcement of any
assessment or penalty or otherwise, all such liability being, by the acceptance
hereof and as part of the consideration for the issue hereof, expressly waived
and released.

                ISSUE, DESCRIPTION, EXECUTION, REGISTRATION AND
                             EXCHANGE OF DEBENTURES


                 SECTION 2.01.  Designation, Amount and Issue of Debentures.
The Debentures shall be designated as 1994-1 Series Convertible Subordinated
Debentures.  Debentures in the aggregate principal amount of $21,312.50 upon
the execution of this Indenture, or from time to time thereafter, may be
executed by the Company and delivered to the Trustee for authentication, and
the Trustee shall thereupon authenticate and deliver said Debentures to or upon
the written order of the Company, signed by its Chairman of the Board,
President or any Vice President and its Treasurer, Assistant Treasurer,
Secretary or Assistant Secretary, without any further action by the Company
hereunder.

                 Interest on the unpaid principal amount of each Debenture
shall be due and payable on each Interest Payment Date after the Issuance Date
of such Debenture on an annualized basis at the Interest Rate in effect from
time to time during the period or any part thereof as to which interest is
payable on such Interest Payment Date.   As soon as practicable after each
Interest Payment Date occurring on or after the date of original issuance, the
Company shall deliver an Officers' Certificate to the Trustee setting forth the
Interest Rate or Interest Rates applicable to the interest payment period
ending on such Interest Payment Date.  As soon as practicable after each
Interest Payment Date the Company will mail to the Debentureholders at their

<PAGE>   22
addresses appearing on the Debenture register notice indicating the Interest
Rate or Interest Rates applicable to the interest payment period ending on such
Interest Payment Date.  Interest shall be calculated on the basis of a 365 day
year.

                 Notwithstanding the foregoing, in no event will interest be
payable on a Debenture to the extent it is in excess of the maximum allowable
interest rate under applicable law.  If the interest payable to any holder or
holders of Debentures is to be calculated at a rate lower than the Interest
Rate, the Company shall promptly deliver to the Trustee an Officers'
Certificate certifying to the lower rate and an Opinion of Counsel that such
interest rate is the maximum allowable interest rate under applicable law.

                 Except as provided in Section 2.06, the aggregate principal
amount of Debentures authorized by this Indenture is limited to the amount set
forth in Section 2.01.

                 Principal of and interest on the Debentures shall be payable
in such coin or currency of the United States of America as at the time of
payment shall be legal tender for the payment of public and private debts.

                 SECTION 2.02.  Form of Debentures.  The Debentures and the
certificate of authentication to be borne by the Debentures shall be
substantially of the tenor and purport as in this Indenture above recited.  Any
of the Debentures may have imprinted thereon such legends or endorsements as
the Board of Directors of the Company may deem appropriate and as are not
inconsistent with the provisions of this Indenture, or as may be required to
comply with any law or with any rule or regulation, or to conform to usage.

                 SECTION 2.03.  Denomination and Date of Debentures.  The
Debentures shall be issuable only as registered Debentures without coupons in
such denominations as the Company shall approve, such approval to be evidenced
by the execution thereof, and shall be numbered, lettered, or otherwise
distinguished in such manner as the Company may deem appropriate and as is not
inconsistent with the provisions of this Indenture, or as may be required to
comply with any law or with any rule or regulation, or to conform to usage.

                 Every Debenture shall be dated the date of its authentication
and shall bear interest from the Issuance Date or from the last Interest
Payment Date to which interest has been paid.

                 The interest installment on any Debenture which is payable on
any Interest Payment date shall be paid to the person in whose name said
Debenture (or any Debenture or Debentures





                                       15
<PAGE>   23
evidencing the same debt) is registered at the close of business on the Record
Date for such interest installment at the address appearing on the Debenture
register or to such other address as that person shall have notified the
Company and the Debenture registrar in writing prior to such Record Date,
except if and to the extent the Company shall default in the payment of the
interest due on such Interest Payment Date, in which case such defaulted
interest shall be paid to the persons in whose names outstanding Debentures are
registered at the close of business on the business day next preceding the date
of payment or at the option of the Company on a subsequent record date (which
shall not be less than five business days preceding the date of payment of
defaulted interest) established for such purpose by notice given by mail by or
on behalf of the Company to the holders of the Debentures not less than fifteen
days preceding such subsequent record date, provided that in the case of any
defaulted interest on a Debenture converted subsequent to a Record Date,
interest shall be paid to the registered holder of the converted Debenture on
the date immediately prior to the Conversion Date.  The term "Record Date" as
used in this Indenture with respect to any Interest Payment Date shall mean the
day (whether or not a business day) next preceding such Interest Payment Date.

                 SECTION 2.04.  Execution of Debentures.  The Debentures shall
be signed (manually or in facsimile) in the name and on behalf of the Company
by its Chairman of the Board, President or one of its Vice Presidents under its
corporate seal (which may be printed, engraved or otherwise reproduced thereon,
by facsimile or otherwise) attested by the manual or facsimile signature of its
Secretary or one of its Assistant Secretaries.  Only such Debentures as shall
bear thereon a certificate of authentication substantially in the form
hereinbefore recited, executed by manual signature by the Trustee, shall be
entitled to the benefits of this Indenture or be valid or obligatory for any
purpose.  Such certificate upon any Debenture executed by the Company shall be
conclusive evidence that the Debenture so authenticated has been duly
authenticated and delivered hereunder and that the holder is entitled to the
benefits of this Indenture.

                 In case any officer of the Company who shall have signed any
of the Debentures shall cease to be such officer before the Debentures so
signed shall have been authenticated and delivered, or disposed of by the
Company, such Debentures nevertheless may be authenticated and delivered or
disposed of as though the person who signed such Debentures had not ceased to
be such officer of the Company; and any Debenture may be signed on behalf of
the Company by such persons as, at the actual date of the execution of such
Debenture, shall be the proper officers of the Company, although at the date of
the execution of this Indenture any such person was not as officer.

                 At any time and from time to time after the execution and
delivery of this Indenture, the Company may deliver Debentures executed by the
Company to the Trustee for authentication; and the Trustee shall authenticate
and deliver such Debentures as in this Indenture provided and not otherwise.

                 SECTION 2.05.  Registration, Registration of Transfer and
Exchange of Debentures.  The Company will keep at the office or agency to be
maintained by the Company as provided in Section 6.02 a register or registers,
in which, subject to such reasonable regulations as it may prescribe, it will
register Debentures and any permitted transfers of Debentures.  The Company
shall serve as its own Debenture registrar until such time as another registrar
may be appointed.

                 Upon surrender for registration of any permitted transfer of
any Debenture at any such office or agency, the Company shall execute and the
Trustee shall authenticate and deliver in the name of the transferee or
transferees a new Debenture or Debentures for a like aggregate principal amount
of authorized denominations.

                 Debentures may be exchanged for a like aggregate principal
amount of other authorized denominations.  Debentures to be exchanged shall be
surrendered for that purpose at any office or agency to be maintained for such
purpose by the Company as provided in Section 6.02, and the Company shall
execute and the Trustee shall authenticate and deliver in exchange therefor the
Debenture or Debentures which the Debentureholder making the exchange shall be
entitled to receive, bearing serial numbers not contemporaneously outstanding.

                 All Debentures presented for registration of transfer,
exchange, redemption or payment shall (if so required by the Company or the
Trustee) be duly endorsed by, or be accompanied by instruments of transfer in
form satisfactory to the Company and to the Trustee duly executed by, the
registered holder or his duly authorized attorney.

                 Any registration of transfer or exchange shall be without
charge, except that the Company may require payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in relation
thereto.

                 The Company shall not be required to register the transfer of
any Debenture not made in accordance with Section 10.06 hereof.

                 SECTION 2.06.  Mutilated, Destroyed, Lost or Stolen
Debentures.  In case any temporary or definitive Debenture shall become
mutilated or be destroyed, lost or stolen, the Company in its discretion may
execute, and upon its request the Trustee shall





                                       17
<PAGE>   25
authenticate and deliver, a new Debenture, bearing a serial number not
contemporaneously outstanding, in exchange and substitution for the mutilated
Debenture or in lieu of and substitution for the Debenture so destroyed, lost
or stolen.  In every case, the applicant for a substituted Debenture shall
furnish to the Company and to the Trustee such security or indemnity as may be
required by them to save each of them harmless, and, in every case of
destruction, loss or theft, the applicant shall also furnish to the Company and
to the Trustee evidence to their satisfaction of the destruction, loss or theft
of such Debenture and of the ownership thereof.

                 The Trustee shall authenticate any such substituted Debenture
and deliver the same upon the written request or authorization of any
Responsible Officer of the Company.  Upon the issuance of any substituted
Debenture, the Company may require the payment of a sum sufficient to cover any
tax or other governmental charge that may be imposed in relation thereto and
any other expenses connected therewith.  In case any Debenture which has
matured or is about to mature shall have become mutilated or be destroyed, lost
or stolen, the Company may, instead of issuing a substitute Debenture, pay or
authorize the payment of the same (without surrender thereof except in the case
of a mutilated Debenture) if the applicant for such payment shall furnish the
Company, the Trustee and any paying agent with such security or indemnity as
they may require to save each of them harmless and, in case of destruction,
loss or theft, evidence to the satisfaction of the Company and the Trustee of
the destruction, loss or theft of such Debenture and of the ownership thereof.

                 Every substituted Debenture issued pursuant to the provisions
of this Section 2.06 by virtue of the fact that any Debenture is destroyed,
lost or stolen shall constitute an additional contractual obligation of the
Company, whether or not the destroyed, lost or stolen Debenture shall be found
at any time, and shall be entitled to all the benefits of this Indenture
equally and proportionately with any and all other Debentures duly issued
hereunder.  All debentures shall be held and owned upon the express condition
that the foregoing provisions are exclusive with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Debentures and shall preclude
(to the extent lawful) any and all other rights or remedies with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Debentures.


                 SECTION 2.07.  Temporary Debentures.  Pending the preparation
of definitive Debentures, the Company may execute and the Trustee shall
authenticate and deliver temporary Debentures.  Temporary Debentures shall be
issuable in any authorized denomination, and substantially in the form of the
definitive Debentures but with such omissions, insertions and variations as





                                       18
<PAGE>   26
may be appropriate for temporary Debentures, all as may be determined by the
officers of the Company, as evidenced by their execution thereof.  Every such
temporary Debenture shall be authenticated by the Trustee upon the same
conditions and in substantially the same manner, and with the same effect, as
the definitive Debentures.  Without unreasonable delay, the Company will
execute and deliver to the Trustee definitive Debentures and thereupon any or
all temporary Debentures may be surrendered in exchange therefor, at the
principal office of the Trustee, and the Trustee shall authenticate and deliver
in exchange for such temporary Debentures an equal aggregate principal amount
of definitive Debentures.  Such exchange shall be made by the Company at its
own expense and without any charge therefor except that the Company may require
payment of a sum sufficient to cover any transfer tax or similar governmental
charge that may be imposed in relation thereto.  Until so exchanged, the
temporary Debenture shall in all respects be entitled to the same benefits
under this Indenture as definitive Debentures authenticated and delivered
hereunder.


                 SECTION 2.08.  Cancellation of Debentures.  All Debentures
surrendered for the purpose of payment, conversion, exchange or registration of
transfer may, if surrendered to the Company or any paying or conversion agent,
be delivered to the Trustee for cancellation or, if surrendered to the Trustee,
shall be canceled by it, and no Debentures shall be issued in lieu thereof
except as expressly permitted by any of the provisions of this Indenture.  The
Trustee shall, upon request of the Company, either deliver canceled Debentures
or a certificate of destruction thereof to the Company.


                 SECTION 2.09.  Benefits of Indenture Provisions.  Nothing in
this Indenture or in the Debentures, expressed or implied, shall give or be
construed to give any person, firm or corporation, other then the parties
hereto and any paying agent, any conversion agent and the holders of Debentures
and, to the extent provided in Article Four, the holders of Senior
Indebtedness, any legal or equitable right, remedy or claim under or in respect
of this Indenture, or under any covenant, condition or provision herein
contained; all the covenants, conditions and provisions contained in this
Indenture or in the Debentures being for the sole benefit of the parties hereto
and any paying agent, any conversion agent and the holders of the Debentures
and, to the extent provided in Article Four, the holders of Senior
Indebtedness.


                 SECTION 2.10.  Maintenance of Office or Agency by Trustee.
The Trustee will maintain an office or agency in Jackson, Mississippi where
Debentures may be presented or





                                       19

surrendered for payment of principal and interest or conversion and where
notices and demands to or upon the Company in respect of the Debentures or of
this Indenture may be served, which shall initially be located at One Deposit
Guaranty Plaza, Jackson, Mississippi 39205.

                 SECTION 2.11.  Condition to Issuance of Debentures.  The
issuance of any Debenture hereunder upon exercise of a Debenture Option issued
pursuant to the Company's 1988 Long Term Incentive Plan shall be conditioned
upon the execution by the person who receives such Debenture of a written
agreement agreeing that any of the Company's Convertible Preferred Stock
issuable upon conversion of the Debenture shall not be transferable other than
by will or the laws of descent and distribution or pursuant to a qualified
domestic relations order as defined by the Internal Revenue Code of 1986, as
amended, or Title I of the Employee Retirement Income Security Act, or the
rules thereunder.  Such agreement may specifically provide that the designation
of a beneficiary shall not constitute a prohibited transfer.

                 particular Debenture pursuant to Section 5.02(a) hereof, the
                 Company may at its sole option prepay such Debenture at any
                 time thereafter, if the Company mails notice of prepayment not
                 less than 30 nor more than 60 days prior to the date fixed for
                 such prepayment to the Debentureholder at his last registered
                 address, and the Trustee.  Any Debenture which is prepaid
                 pursuant to this Section 3.01(a) shall cease to bear interest
                 from the date fixed for prepayment.  Notice of prepayment
                 pursuant to this Section 3.01(a) shall state (i) the
                 prepayment date, (ii) the prepayment price, (iii) that the
                 Debentures must be surrendered to the paying agent for payment
                 and (iv) that interest on the Debentures ceases to accrue on
                 and after the prepayment date.

                 (b)  Installments of interest which mature on or prior to the
                 prepayment date shall be payable to the holders of such
                 Debentures registered as such on the relevant Record Dates
                 according to their terms and to the provisions of Section 2.03
                 hereof.

                 SECTION 3.02.  Redemption of Debentures.  Providing all other
debentures issued under the Plan are called on an Interest Payment Date the
Debentures are redeemable at the Company's





                                       20
<PAGE>   28
option, on that same Interest Payment Date, in whole or in part, upon mailing a
notice of redemption not less than 12 months prior to the date fixed for such
redemption to the holder or holders of the Debentures to be redeemed at such
holder's or holders' last registered addresses.

                 Each Debenture is redeemable at a redemption price of 100% of
the principal amount thereof, together with accrued interest to the date fixed
for redemption.  Installments of interest which mature on or prior to the
redemption date shall be payable to the holders of such Debentures registered
as such on the relevant Record Dates according to their terms and to the
provisions of Section 2.03 hereof.  The Debentureholder may convert its
Debenture at any time prior to and on the redemption date, subject to the
limitations on conversion privileges set forth in other provisions of this
Indenture.

                 At least 12 months but not more than 18 months before a
redemption date, the Company shall mail a notice of redemption by first-class
mail to each holder of the Debentures to be redeemed and to the Trustee.  The
notice shall state (i) the redemption date, (ii) the redemption price, (iii) if
less than all outstanding Debentures are to be redeemed, the identification
(and, in the case of partial redemption, the respective principal amounts) of
the Debentures to be redeemed, (iv) that the Debentures called for redemption
may be converted at any time prior to and on the redemption date, (v) the
conditions prerequisite to conversion of Debentures, (vi) that Debentures
called for redemption must be surrendered to the paying agent to collect the
redemption price, and (vii) that interest on the Debentures ceases to accrue on
and after the redemption date.  At the Company's request, the Trustee shall
give notice of redemption in the Company's name and at its expense.

                 Subject to the provisions of Section 3.01 hereof, once notice
of redemption is mailed, the Debentures called for redemption become due and
payable on the redemption date and at the redemption price, and upon surrender
to the paying agent, such Debentures shall be paid at the redemption price,
plus accrued interest to the redemption date.

                 SECTION 3.03.  Deposit of Monies for Redemption or Prepayment.
Prior to any redemption or prepayment date, the Company shall deposit with the
paying agent money sufficient to pay the redemption or prepayment price of and
accrued interest on all Debentures to be redeemed or prepaid.  The paying agent
shall return to the Company any money not required for that purpose because of
conversion of Debentures.

                 If any Debenture called for redemption or prepayment shall not
be so paid upon surrender thereof for redemption or prepayment, the principal
shall, until paid, bear interest from





                                       21
<PAGE>   29
the redemption or prepayment date at the Interest Rate borne by the Debenture.

                 SECTION 3.04.  Limitation on Prepayment.  Except as provided
in Sections 3.01 and 3.02 hereof, no Debenture may be prepaid or redeemed by
the Company prior to the Due Date without the written consent of the holder
thereof.

                 SECTION 3.05.  Holder's Right to Elect Redemption.  Commencing
on the first Interest Payment Date occurring more than one year after the
Issuance Date of any Debenture, the holder of such Debenture or such holder's
legal successor may elect to have the Company redeem the Debenture on any
Interest Payment Date, by surrender of the Debenture to the Company at least 10
days prior to such Interest Payment Date at the office of the Company, or at an
office or agency established for such purpose, duly endorsed or accompanied by
a written instrument of transfer in form satisfactory to the Company and
accompanied by a written notice of election to receive payment of the
Debenture.  The amount of such payment shall be equal to the unpaid principal
portion of the Debenture plus accrued but unpaid interest on the Debenture
through the Interest Payment date.  The Company shall hand deliver or mail by
first class mail to the Debentureholder a check on the Interest Payment Date in
payment of the amount due in redemption of the Debenture.

                          SUBORDINATION OF DEBENTURES

                 SECTION 4.01.  Agreement That Debentures Be Subordinate.  The
Company covenants and agrees, and each holder of a Debenture issued hereunder
by his acceptance thereof likewise covenants and agrees, that all Debentures
issued hereunder shall be issued subject to the provisions of this Article
Four; and each person holding any Debenture, whether upon original issue or
upon transfer or assignment thereof, accepts and agrees to be bound by such
provisions.

                 SECTION 4.02.  Subordination to Senior Indebtedness.  Anything
in this Indenture or in any Debenture to the contrary notwithstanding, the
indebtedness evidenced by each Debenture shall be subordinate and junior, to
the extent and in the manner hereinafter set forth, to all Senior Indebtedness:

                 (a)  In the event of any insolvency or bankruptcy proceedings,
                 and any receivership, liquidation, reorganization or other
                 similar proceedings in connection therewith, relative to the
                 Company or to its creditors, as such, or to its property, and
                 in the event of any proceedings for voluntary liquidation,

                 dissolution, or other winding-up of the Company, whether or
                 not involving insolvency or bankruptcy, then the holders of
                 Senior Indebtedness shall be entitled to receive payment is
                 full of all principal of and interest on all Senior
                 Indebtedness, or to have provision made for such payment,
                 before the holders of the Debentures are entitled to receive
                 any payment on account of principal of or interest on the
                 Debentures, and to that end (but subject to the power of a
                 court of competent jurisdiction to make other equitable
                 provisions reflecting the rights conferred by these
                 subordination provisions upon the Senior Indebtedness and the
                 holders thereof with respect to the subordinated indebtedness
                 represented by the Debentures and the holders thereof by a
                 lawful plan of reorganization under applicable bankruptcy law)
                 the holders of Senior Indebtedness shall be entitled to
                 receive for application in payment thereof any payment or
                 distribution of any kind or character, whether in cash or
                 property or securities, which may be payable or deliverable in
                 any such proceedings in respect of the Debentures, except
                 securities which are subordinate and junior in right or
                 payment to the payment of all Senior Indebtedness then
                 outstanding;

                 (b)  If any Senior Indebtedness matures by lapse of time,
                 acceleration or otherwise, and is not immediately paid,
                 refunded or replaced by new indebtedness, then all principal
                 of, (and premium, if any) and interest on all such matured
                 Senior Indebtedness shall first be paid in full, or such
                 payment shall be duly provided for, before any payment on
                 account of principal or interest is made upon, or acquisition
                 is made of any of, the Debentures;

                 (c)  Each Debentureholder, by his acceptance of a Debenture
                 issued hereunder (i) irrevocably authorizes and empowers
                 (without imposing any obligation on) each holder of Senior
                 Indebtedness (hereinafter in this clause (c) called a "Senior
                 Holder") at the time outstanding and such Senior Holder's
                 representatives to demand, sue for, collect, receive and
                 receipt for such Debentureholder's ratable share of all
                 payments and distributions in respect of the Debentures which
                 are required to be paid or delivered to the Senior Holders as
                 provided in clause (a) above, and to file and prove all claims
                 therefor and take all such other action (including the right
                 to vote such Debentureholder's ratable share of the
                 Debentures) in the name of such Debentureholder or otherwise,
                 as such Senior Holder or such Senior Holder's representatives
                 may determine to be necessary or appropriate for the
                 enforcement of clause (a) above, provided, however, that no
                 action may be





                                       23
<PAGE>   31
                 taken by any Senior Holder or such Senior Holder's
                 representatives pursuant to the authorization conferred by
                 this item (i) of this clause (c) unless written notice shall
                 have been given by such Senior Holder or such Senior Holder's
                 representatives to a Debentureholder requesting such
                 Debentureholder to take such action and such Debentureholder
                 shall not have taken such action within 15 days after the
                 giving of such notice; and (ii) agrees to execute and deliver
                 to each Senior Holder and such Senior Holder's representatives
                 all such further instruments confirming the above
                 authorization, and all such powers of attorney, proofs of
                 claim, assignments of claim and other instruments, and to take
                 all such other action as may be requested by such Senior
                 Holder or such Senior Holder's representatives in order to
                 enable such Senior Holder to enforce all claims upon or in
                 respect of such Debentureholder's ratable share of the
                 Debentures.

Notwithstanding any of the foregoing clauses (a) through (c) of this Section
4.02, nothing herein shall prevent the Company from prepaying any Debenture
prior to the Due Date under circumstances when the provisions of clause (a) or
clause (b) of this Section 4.02 shall not be applicable.

                 SECTION 4.03.  Payment to Holders of Senior Indebtedness of
Certain Amounts Received by Debentureholders.  In the event that,
notwithstanding the provisions of Section 4.02 prohibiting such distribution or
payment, any distribution of assets of the Company or payment by or on behalf
of the Company of any kind or character, whether in cash, property or
securities, to which the holders of the Debentures or the Trustee would be
entitled but for the provisions of this Article Four prohibiting such
distribution or payment, shall be received by the Trustee or the holders of the
Debentures before the principal of and interest on all Senior Indebtedness is
paid in full, or provision is made for its payment, such distribution or
payment shall be held in trust for the benefit of, and shall be paid over or
delivered to, the holders of such Senior Indebtedness or their representative
or representatives, or to the trustee or trustees under any indenture pursuant
to which any instruments evidencing any of such Senior Indebtedness may have
been issued, ratably according to the aggregate amounts remaining unpaid on
account of the Senior Indebtedness held or represented by each, for application
to the payment of all Senior Indebtedness remaining unpaid to the extent
necessary to pay the principal of and interest on all such Senior Indebtedness
in full, after giving effect to any concurrent distribution or payment, or
provision therefor, from any source, to the holders of such Senior Indebtedness
or their representatives or trustees.





                                       24
<PAGE>   32
                 SECTION 4.04.  Notice to Trustee of Specified Events; Reliance
on Certificate of Liquidating Agent.  The Company shall give prompt written
notice to the Trustee of any insolvency or bankruptcy proceeding in respect of
the Company and of any proceedings for voluntary liquidation, dissolution or
other winding up of the Company (whether or not involving insolvency or
bankruptcy), within the meaning of Section 4.02(a), and of any event which
pursuant to Section 4.02(b) would prevent payment by the Company on account of
the principal of or interest on the Debenture.  The Trustee, subject to the
provisions of Section 9.01, shall be entitled to assume that no such event has
occurred unless the Company, or a holder of Senior Indebtedness, or any trustee
or representative therefor, has given such notice.  The Trustee shall not be
charged with knowledge of the curing of any event or of the elimination of the
act or condition preventing any payment by the Company unless and until the
Trustee shall have received an Officers' Certificate to such effect; and the
Company shall deliver such an Officers' Certificate promptly after the curing
of any such default or the elimination of any such act or condition.

                 Upon any distribution of assets of the Company or payment by
or on behalf of the Company referred to in this Article Four, the Trustee and
the holders of the Debentures shall be entitled to rely upon any order or
decree of a court of competent jurisdiction in which any proceedings of the
nature referred to in Section 4.02(a) are pending, and the Trustee, subject to
the provisions of Section 9.01 hereof, and the holders of the Debentures shall
be entitled to rely upon a certificate of the liquidating trustee or agent or
other person making any distribution to the Trustee or to the holders of the
Debentures for the purpose of ascertaining the persons entitled to participate
in such distribution, the holders of the Senior Indebtedness and other
indebtedness of the Company, the amount thereof or payable thereon, the amount
or amounts paid or distributed thereon and all other facts pertinent thereto or
to this Article Four.  In the event that the Trustee determines, in good faith,
that further evidence is required with respect to the right of any person as a
holder of Senior Indebtedness to participate in any payment or distribution
pursuant to this Article Four, the Trustee may request such person to furnish
evidence to the reasonable satisfaction of the Trustee as to the amount of
Senior Indebtedness held by such person, as to the extent to which such person
is entitled to participate in such payment or distribution, and as to other
facts pertinent to the rights of such person under this Article Four, and if
such evidence is not furnished, the Trustee may defer any payment to such
person pending judicial determination as to the right of such person to receive
such payment.

                 The Trustee, however, shall not be deemed to owe any fiduciary
duty to the holders of Senior Indebtedness but shall





                                       25
<PAGE>   33
have only such obligations to such holders as are expressly set forth in this
Article Four.

                 SECTION 4.05.  Subrogation.  Subject to the payment in full of
the principal of and interest on all Senior Indebtedness, the holders of the
Debentures (together with the holders of any other indebtedness of the Company
which is subordinate in right of payment to the payment of other indebtedness
of the Company, but is not subordinate in right of payment to the Debentures
and by its terms grants such right of subrogation to the holders thereof) shall
be subrogated to the rights of the holders of Senior Indebtedness to receive
distributions of assets of the Company, or payments by or on behalf of the
Company, made on the Senior Indebtedness, until the principal of and interest
on the Debentures shall be paid in full; and, for the purpose of such
subrogation, no distributions or payments to the holders of Senior Indebtedness
of any cash, property or securities to which the holders of the Debentures or
the Trustee would be entitled except for the provisions of this Article Four,
and no payment over pursuant to the provisions of this Article Four to the
holders of Senior Indebtedness by the holders of the Debentures or the Trustee
shall, as between the Company, its creditors other than the holders of Senior
Indebtedness and the holders of Debentures, be deemed to be a payment by the
Company to or on account of Senior Indebtedness, it being understood that the
provisions of this Article Four are, and are intended, solely for the purpose
of defining the relative rights of the holders of the Debentures, on the one
hand, and the holders of Senior Indebtedness, on the other hand.

                 SECTION 4.06.  Obligation to Pay Not Impaired.  Nothing
contained in this Article Four or elsewhere in this Indenture, or in the
Debentures, is intended to or shall alter or impair, as between the Company,
its creditors other than the holders of Senior Indebtedness, and the holders of
the Debentures, the obligation of the Company, which is absolute and
unconditional, to pay to the holders of the Debentures the principal of and
interest on the Debentures at the time and place and at the rate and in the
currency therein prescribed, or to affect the relative rights of the holders of
the Debentures and creditors of the Company other than the holders of Senior
Indebtedness, nor shall anything herein or therein prevent the Trustee or the
holder of any Debenture from exercising all remedies otherwise permitted by
applicable law upon default under this Indenture, subject to the rights, if
any, under this Article Four of the holders of Senior Indebtedness to receive
cash, property or securities otherwise payable or deliverable to the holders of
the Debentures.

                 SECTION 4.07.    Reliance by Senior Indebtedness on
Subordination Provisions.  Each holder of any Debenture by his acceptance
thereof acknowledges and agrees that the foregoing subordination provisions
are, and are intended to be, an





                                       26
<PAGE>   34
inducement and a consideration to each holder of any Senior Indebtedness,
whether such Senior Indebtedness was created or acquired before or after the
issuance of the Debentures, to acquire and continue to hold, or to continue to
hold, such Senior Indebtedness, and such holder of Senior Indebtedness shall be
deemed conclusively to have relied on such subordination provisions in
acquiring and continuing to hold, or in continuing to hold, such Senior
Indebtedness.

                 SECTION 4.08.  Certain Payments and Credits Permitted.
Nothing contained in this Article Four or elsewhere in this Indenture, or in
any of the Debentures, shall (a) affect the right of the Company to make or
prevent the Company from making payment of the principal of or interest on the
Debentures, or from depositing with the Trustee or any paying agent monies for
such payments, not then contrary to the conditions described in Section 4.02,
(b) prevent the application by the Trustee or any paying agent of any monies so
deposited with it under this Indenture to the payment of or on account of the
principal of or interest on the Debentures unless the Trustee has knowledge of
a default on the Senior Indebtedness, or (c) prevent the retention by the
holders of Debentures of monies so applied and paid to them on account of the
principal of or interest on the Debentures, whether or not at the time of such
application described in (b) or payment described in (c) payment of principal
of or interest on the Debentures would then be precluded pursuant to Section
4.02.

                 SECTION 4.09.  Subordination Not to be Prejudiced by Certain
Acts.  No right of any present or future holder of any Senior Indebtedness of
the Company to enforce subordination as herein provided shall at any time in
any way be prejudiced or impaired by any act or failure to act on the part of
the Company or by any act or failure to act by any such holder, or by any
noncompliance by the Company with the terms, provisions and covenants of this
Indenture, regardless of any knowledge thereof any such holder may have or be
otherwise charged with.

                 SECTION 4.10.    Trustee Authorized to Effectuate
Subordination.  Each holder of Debentures by his acceptance thereof authorizes
and directs the Trustee on his behalf to take such action as may be necessary
or appropriate to acknowledge or effectuate the subordination as provided in
this Article Four and appoints the Trustee his attorney-in-fact for any and all
such purposes.

                 SECTION 4.11.    Trustee's Rights Regarding Senior
Indebtedness Held By It, Etc.  The Trustee shall be entitled to all the rights
set forth in this Article Four in respect of any Senior Indebtedness at any
time held by it, to the same extent as any other holder of Senior Indebtedness,
and nothing in Section 9.13 or elsewhere in this Indenture shall deprive the
Trustee of any of its rights as such holder.  Nothing in this Article Four





                                       27
<PAGE>   35
shall apply to claims of, or payments to, the Trustee under or pursuant to
Section 9.06 of this Indenture.

                 SECTION 4.12.    Trustee and Paying Agents Not Chargeable with
Knowledge Until Notice.  Notwithstanding any of the provisions of this Article
Four or any other provision of this Indenture, the Trustee and any paying agent
shall not at any time be charged with knowledge of the existence of any facts
which would prohibit the making of any payment of monies to or by the Trustee
or any paying agent, unless and until the Trustee or such paying agent, as the
case may be, shall have received written notice thereof from the Company or a
holder of Senior Indebtedness, or any trustee therefor; and, prior to the
receipt of any such written notice, the Trustee, subject to the provisions of
Section 9.01, and any paying agent shall be entitled to assume that no such
facts exist.  If at lease twenty-four hours prior to the date upon which by the
terms hereof any such monies may become payable for any purpose (including,
without limitations, the payment of either the principal of or the interest on
any Debenture) the Trustee or paying agent, as the case may be, shall not have
received with respect to such monies the notice provided for in this Section
4.12, then, anything herein contained to the contrary notwithstanding, the
Trustee shall have full power and authority to receive such monies and to apply
the same to the purpose for which they were received and shall not be affected
by any notice to the contrary which may be received by it on or after the
commencement of such twenty-four hour period.

                 SECTION 4.13.  1984-A, 1985-A, 1986-A, 1982-A, 1982-B, 1982-C,
1982-D, 1983-A, 1984-B, 1987-A, 1988-A, 1988-1, 1989-A, 1989-1, 1989-2, 1990-1,
1990-2, 1991-1, 1991-2 Series and 1992-1 Series Convertible Subordinated
Debentures.  Anything in this Indenture or in the Debentures to the contrary
notwithstanding, the Debentures shall be neither subordinate nor superior in
right of payment to the 1984-A Series Convertible Subordinated Debentures due
1994, issued by the Company under an Indenture dated as of August 17, 1984, or
the 1985-A Series Convertible Subordinated Debentures due 1995, issued by the
Company under an Indenture dated as of August 13, 1985, or the 1986-A Series
Convertible Subordinated Debentures due 1996, issued by the Company under an
Indenture dated as of August 11, 1986, or the 1982-A, 1982-B, 1982-C, 1982-D,

                                  ARTICLE FIVE

                            CONVERSION OF DEBENTURES

                 SECTION 5.01.    Conversion Privilege; Conversion Price.
Subject to and upon compliance with the provisions of this Article Five, at the
option of the holder thereof, any Debenture or portion thereof may, at any time
more than six months after the date of the award of the debenture option
pursuant to which the Debenture was purchased and at or before the close of
business on the Due Date (or, in case such Debenture shall be called for
redemption prior to the Due Date and the Company does not default in timely
payment of the redemption price, then until the close of business on the date
fixed for redemption) be converted at the principal amount thereof, or of such
portion thereof, into fully paid and nonassessable whole shares of 1994-1
Series Stock, at the conversion price of $21.3125 per share (the "conversion
price").  The conversion price shall not be subject to adjustment.  Rights with
respect to fractional share interests shall be governed by Section 5.04.

                 SECTION 5.02.    Conversion Period; Limitation on Exercise.
The conversion privilege set forth in Section 5.01 shall also be limited as
described below.

                 (a)      Pledge of Debentures.  At any time that a Debenture
                 is pledged or otherwise hypothecated as collateral for a loan
                 to any person, the conversion privilege for that Debenture may
                 not be exercised by any person.  If such pledge or
                 hypothecation is not made in compliance with Section 10.06
                 hereof, the conversion privilege for such Debenture shall
                 simultaneously with such pledge or hypothecation wholly and
                 permanently terminate.  As soon as practicable, the Company
                 shall give notice to the





                                       29
<PAGE>   37
                 Trustee and any conversion agent of such prohibited pledge or
                 hypothecation.  If such pledge or hypothecation is made in
                 compliance with Section 10.06, the conversion privilege for
                 that Debenture shall be exercisable upon receipt by the
                 Company, the Trustee and the conversion agent from the
                 Debentureholder and the person to whom the Debenture has been
                 pledged or hypothecated of notice satisfactory to the Company
                 that the pledge or hypothecation has been fully and completely
                 discharged and released and no pledge or hypothecation of the
                 Debenture has been substituted or has otherwise been created.
                 If such pledge or hypothecation is made in compliance with
                 Section 10.06 and the Debenture is transferred to a person
                 foreclosing on such Debenture, the conversion privilege for
                 such Debenture shall simultaneously with such foreclosure
                 wholly and permanently terminate.  Unless and until the
                 Trustee and the conversion agent shall have received notice in
                 writing of a prohibited pledge or hypothecation of the
                 Debenture or a foreclosure, the Trustee and conversion agent
                 shall be entitled in all respects to conclusively assume that
                 no such pledge, hypothecation or foreclosure has taken place.

                 (b)  Suspension Pending Listing and/or Registration.  Anything
                 herein to the contrary notwithstanding, if at any time the
                 Board of Directors determines, in its discretion, that the
                 listing, registration, or qualification upon any securities
                 exchange or under any state or Federal law of 1994-1 Series
                 Stock into which the Debentures are convertible or of Common
                 Stock into which the 1994-1 Series Stock is convertible, or
                 that the consent or approval of any governmental regulatory
                 body, is necessary or desirable as a condition of, or in
                 connection with, the issue of such shares, (1) the Company
                 will in good faith and at its own expense as expeditiously as
                 possible endeavor to secure such listing, registration,
                 qualification, consent or approval, or take such other action,
                 as the case may be, and (2) the conversion privilege of the
                 Debentures may not be exercised in whole or in part until such
                 listing, registration, qualification, consent or approval
                 shall have been effected or obtained and the same shall have
                 been free of any conditions not acceptable to the Board of
                 Directors.

                 In the case of any suspension of the conversion privilege
pursuant to this Section 5.02(b) that occurs or will continue after the
Debentures first become convertible, the Company shall promptly deliver to the
Trustee and the conversion agent an Officers' Certificate stating that such
suspension has occurred and the reason therefor and shall promptly mail notice
of





                                       30
<PAGE>   38
such suspension and the reason therefor to the holders of the Debentures at
their addresses as they appear on the Debenture register.  Upon termination of
any such suspension, the Company shall promptly deliver to the Trustee and the
conversion agent an Officers' Certificate stating that such suspension has
terminated and shall promptly mail notice thereof to the holders of the
Debentures at their addresses as they appear on the Debenture register.

                 (c)      Effect of Suspension.  Suspension of the right to
                 exercise the conversion privilege shall not reduce any other
                 rights under a Debenture.

                 SECTION 5.03.    Manner of Exercising Conversion Privilege.
In order to exercise the conversion privilege, the holder of any Debenture to
be converted shall surrender such Debenture to the Company at any office or
agency maintained for that purpose pursuant to Section 2.10 or 6.02,
accompanied by written notice to the Company at such office or agency that the
holder elects to convert such Debenture or a specified portion thereof.
Debentures surrendered for conversion shall, if so required by the Company or
the Trustee, be duly endorsed by, or accompanied by instruments of transfer in
form satisfactory to the Company duly executed by, the registered holder or his
duly authorized attorney.  As promptly as practicable after the receipt of such
notice and the surrender of such Debenture as aforesaid, the Company shall
issue and shall deliver, at the office or agency at which such Debenture is
surrendered or such other place as the holder designates in writing, to such
holder (or, on his written order, in his name and for his benefit to some other
person), a certificate or certificates for the number of shares of 1994-1
Series Stock issuable upon the conversion of such Debenture (or specified
portion thereof), and a check in lieu of any fractional interest in accordance
with the provisions of this Article Five.  Such conversion shall be deemed to
have been effected on the Conversion Date and at such time the rights of the
holder of such Debenture as such Debentureholder shall cease and the person or
persons in whose name or names any certificate or certificates for shares of
1994-1 Series Stock shall be issuable upon such conversion shall be deemed to
have become the holder or holders of record of the shares represented thereby.

                 In the case of any Debenture which is converted in part only,
upon such conversion the Company shall execute and the Trustee shall
authenticate and deliver to or on the order of the holder thereof, at the
expense of the Company, a new Debenture or Debentures of authorized
denominations in principal amount equal to the unconverted portion of such
Debenture.  The conversion privilege of the Debenture converted in part shall
apply to such new Debenture or Debentures.  No partial conversion will be
permitted if, following conversion, the remaining principal amount of the
Debenture would be less than $1,000.00.





                                       31
<PAGE>   39
                 Interest will accrue on Debentures through the day immediately
preceding the date of conversion and will be paid to the holder of the
Debenture (or, on his written order, in his name and for his benefit to some
other person) when his shares of 1992-1 Series Stock are delivered.

                 SECTION 5.04.    Fractional Shares.  Shares of 1994-1 Series
Stock shall be issued upon conversion of Debentures in whole shares only.  If
more than one Debenture shall be surrendered for conversion at one time by the
same holder, the number of shares which shall be issuable upon conversion shall
be computed on the basis of the aggregate principal amount of the Debentures
(or specified portions thereof to the extent permitted hereby) so surrendered.
If any fractional interest in a share would be deliverable upon conversion of
any Debenture, the Company shall make an adjustment therefor by payment in the
form of a check or cash equal in amount to the product obtained by multiplying
the conversion price per share times such fractional interest.

                 SECTION 5.05.  Notice of Certain Corporate Action.  In case:

                 (a)  the Company shall declare a dividend (or any other
                 distribution) on its 1994-1 Series Stock or its Common Stock
                 payable otherwise than in cash or other property out of its
                 retained earnings; or

                 (b)  the Company shall authorize the granting to the holders
                 of its 1994-1 Series Stock or its Common Stock of rights to
                 subscribe for or purchase any shares of capital stock of any
                 class or of any other rights; or

                 (c)      the Company shall authorize any reclassification of
                 the 1992-1 Series Stock or the Common Stock of the Company
                 (other than a subdivision or combination of its outstanding
                 shares of Common Stock), or any consolidation or merger to
                 which the Company is a party and for which approval of any
                 stockholders of the Company is required, or the sale or
                 transfer of all or substantially all of the assets of the
                 Company; or

                 (d)  of the voluntary or involuntary dissolution, liquidation
                 or winding up of the Company;

then the Company shall cause to be filed at the office or offices or agency or
agencies maintained for the purpose of conversion of Debentures pursuant to
Section 2.10 and 6.02, and shall cause to be mailed to the Trustee and to
holders of Debentures, at their last addresses as they shall appear upon the
register provided for in Section 2.05, at least 20 days (or 10 days in any case
specified in clause (a) or (b) above) prior to the applicable





                                       32
<PAGE>   40
record date hereinafter specified, a notice stating (i) the date on which a
record is to be taken for the purpose of such dividend, distribution, rights or
warrants, or, if a record is not to be taken, the date as of which the holders
of its 1994-1 Series Stock or Common Stock, as the case may be, which are to be
entitled to such dividend, distribution, rights or warrants are to be
determined, or (ii) the date on which such reclassification, consolidation,
merger, sale, transfer, dissolution, liquidation or winding up is expected to
become effective, and the date as of which it is expected that record holders
of 1994-1 Series Stock or Common Stock, as the case may be, shall be entitled
to exchange their shares of 1994-1 Series Stock or Common Stock for securities,
cash or other property deliverable upon such reclassification, consolidation,
merger, sale, transfer, dissolution, liquidation or winding up.  Failure to
give notice or any defect therein shall not affect the legality or validity of
any dividend, distribution, right, redistribution, charge, consolidation,
merger, sale, or transfer.  The Trustee shall have no duties with respect to
any notice provided or given to it pursuant to this Section 5.05, except to
exhibit the same to Debentureholders upon request.

                 SECTION 5.06.  Company to Reserve Stock.  The Company shall at
all times reserve and keep available, free from preemptive rights, out of its
authorized but unissued 1994-1 Series Stock, for the purpose of effecting the
conversion of Debentures, the maximum number of shares of 1994-1 Series Stock
then issuable upon the conversion of all outstanding Debentures, and if at any
time the number of authorized but unissued shares of 1994-1 Series Stock shall
not be sufficient to effect such conversions the Company will take such
corporate action as may, in the opinion of its counsel, be necessary to
increase its authorized but unissued shares of 1994-1 Series Stock to such
number of shares as shall be sufficient for such purpose.

                 SECTION 5.07.    Taxes on Conversions.  The Company will pay
any and all taxes (other than any income taxes) that may be payable in respect
of the issue or delivery of shares of 1994-1 Series Stock on conversion of
Debentures pursuant hereto.  The Company shall not, however, be required to pay
any tax which may be payable in respect of any transfer involved in the issue
and delivery of shares of 1994-1 Series Stock in a name other than that of the
holder of the Debenture or Debentures to be converted, and no such issue or
delivery shall be made unless and until the person requesting such issue has
paid to the Company the amount of any such tax or has established, to the
satisfaction of the Company, that such tax has been paid.

                 SECTION 5.08.  Covenant as to Stock.  The Company covenants
that all shares of 1994-1 Series Stock which may be issued upon conversion of
Debentures, and all shares of Common Stock which may be issuable upon
conversion of 1994-1 Series





                                       33
<PAGE>   41
Stock, will upon issue be duly and validly issued and fully paid and
nonassessable and free from all taxes, liens and charges with respect to the
issue thereof.

                 SECTION 5.09.    Provision in Case of Consolidation, Merger or
Sale.  In case of any consolidation of the Company with, or merger of the
Company into, any other corporation or the merger of any other corporation into
the Company (other than a merger in which the Company is the continuing
corporation and in which no change is made in the outstanding 1994-1 Series
Stock of the Company), or in case of any sale or transfer of all or
substantially all of the assets of the Company, the corporation formed by such
consolidation or the corporation which shall have acquired such assets or the
Company (if another corporation shall have merged into the Company) as the case
may be (the "Surviving Corporation"), shall execute and deliver to the Trustee
a supplemental indenture providing that the holder of each Debenture then
outstanding shall have the right thereafter (until the expiration of the
conversion right of such Debenture) to convert such Debenture into the kind and
amount of shares  of stock, other securities, cash or other property receivable
upon such consolidation, merger, sale or transfer by a holder of the number of
shares of 1994-1 Series Stock of the Company into which such Debenture might
have been converted immediately prior to such consolidation, merger, sale or
transfer.  The above provisions of this Section shall similarly apply to
successive consolidations, mergers, sales or transfers.  Notice of the
execution of any such supplemental indenture shall be mailed by the Company at
its cost and expense to the holders of the Debentures as soon as practicable
after the execution of such supplemental indenture.  Failure to give such
notice, or any defects therein, shall not affect the legality or validity of
any supplemental indenture.

                 SECTION 5.10.    Trustee's Disclaimer of Responsibility for
Certain Matters.  Neither the Trustee nor any conversion agent shall be
accountable with respect to the validity or value (or the kind or amount) of
any shares of 1994-1 Series Stock, or of any securities or property, which may
at any time be issued or delivered upon the conversion of any Debenture; and
neither the Trustee nor any conversion agent makes any representation with
respect thereto.  Subject to the provisions of Section 9.01, neither the
Trustee nor any conversion agent shall be responsible for any failure of the
Company to issue, register or deliver any shares of 1994-1 Series Stock or
stock certificates or other securities or property upon the surrender of any
Debenture for the purpose of conversion or to comply with any of the covenants
of the Company contained in this Article Five.  Neither the Trustee nor the
conversion agent has any duty to determine whether any provisions of a
supplemental indenture pursuant to Section 5.09 are correct.

<PAGE>   42
                 SECTION 5.11.    Covenant as to Conversion Rights.  The
Company covenants and agrees that so long as any of the Debentures are
outstanding, it will not amend its Certificate of Incorporation in any way
which would adversely change the conversion rights of the 1994-1 Series Stock
unless such amendment shall have been approved in writing by the holders of not
less than sixty-six and two-thirds percent of all shares of 1994-1 Series Stock
at the time outstanding and by the holders of not less than sixty-six and
two-thirds percent of the aggregate principal amount of the Debentures at the
time outstanding.

                                  ARTICLE SIX

                      PARTICULAR COVENANTS OF THE COMPANY

                 SECTION 6.01.    Payment of Principal and Interest.  The
Company covenants and agrees that it will duly and punctually pay or cause to
be paid the principal of and interest on each of the Debentures at the time and
place and in the manner provided in the Debentures to or upon the written order
of the holders thereof.

                 SECTION 6.02.    Office for Notices, Payments and Conversions.
The Company covenants and agrees, so long as any of the Debentures remain
outstanding, to maintain in Jackson, Mississippi, one or more offices or
agencies where the Debentures may be presented for payment of principal and
interest, for registration of transfer or exchange or for conversion and an
office or agency where notices and demands to or upon the Company in respect of
the Debentures or of this Indenture may be served.  The Company will give to
the Trustee notice of the location of any such offices or agencies and of any
change of location thereof.  In case the Company shall fail to maintain such
office or agency or shall fail to give such notice of the location or of any
change in the location thereof, presentations and demands may be made and
notices may be served at the principal office of the Trustee.

                 SECTION 6.03.  Paying Agents.

                 (a)      Whenever the Company shall have one or more paying
                 agents, it will, prior to each due date of the principal of or
                 interest on any Debentures, deposit with such paying agent a
                 sum sufficient to pay the principal or interest so becoming
                 due.  The Company will promptly notify the Trustee of its
                 action or failure so to act.

                 (b)      Any paying agent appointed by the Company, other than
                 the Trustee, shall be a bank or trust company of the character
                 and with the qualifications set forth in Section 9.09, and the
                 Company covenants and agrees to cause such paying agent to
                 execute and deliver to the Trustee an instrument in which it
                 shall agree with the Trustee, subject to the provisions of
                 this Section, (1)





                                       35
<PAGE>   43
                 that such paying agent shall hold in trust for the benefit of
                 the Debentureholders all sums held by such paying agent for
                 the payment of the principal of or interest on any of the
                 Debentures, (2) that such paying agent shall give to the
                 Trustee notice of any failure by the Company (or any other
                 obligor on the Debentures) to make any payment of the
                 principal of or interest on the Debentures when the same shall
                 be due and payable, and (3) at any time during the continuance
                 of any such default, upon the written request of the Trustee,
                 forthwith pay to the Trustee all sums so held in trust by such
                 paying agent.

                 (c)      If the Company shall at any time act as its own
                 paying agent, then on or before each due date of the principal
                 of or interest on any of the Debentures, it will set aside and
                 segregate and hold in trust for the benefit of the holders of
                 the Debentures a sum sufficient to pay such principal or
                 interest so becoming due, and will notify the Trustee of its
                 action or of any failure to take such action.

                 (d)      Anything in this Section 6.03 to the contrary
                 notwithstanding, the Company may at any time, for the purpose
                 of obtaining the satisfaction and discharge of this Indenture
                 or for any other purpose, pay or cause to be paid to the
                 Trustee all sums held in trust by it or any paying agent as
                 required by this Section, such sums to be held by the Trustee
                 upon the trusts herein contained.

                 (e)  Anything in this Section 6.03 to the contrary
                 notwithstanding, the agreement to hold sums in trust as
                 provided in this Section is subject to the provisions of
                 Sections 14.03 and 14.04 hereof.

                 SECTION 6.04.    Appointment to Fill a Vacancy in Office of

                 SECTION 6.05.    Further Instruments and Acts.  The Company

                 (a)      The Company will, and will cause each Subsidiary to,
                 pay all taxes, assessments and governmental charges





                                       36

                 lawfully levied or assessed upon it, upon its property or any
                 part thereof, or upon its income or profits, or any part
                 thereof, before the same shall become delinquent, and will
                 duly observe and conform to all lawful requirements of any
                 governmental authority relative to any of its property, and
                 all covenants, terms and conditions upon or under which any of
                 its property is held; and within four months after the
                 accruing of any lawful claims or demands for labor, materials,
                 supplies or other objects, which might become a lien or charge
                 upon any of its property or the income therefrom, it will pay
                 or cause to be discharged or make adequate provision to
                 satisfy and discharge the same; provided that nothing in this
                 Section 6.06 or elsewhere in this Indenture contained shall
                 require the Company to observe or conform to any requirements
                 of any governmental authority or to cause to be paid or
                 discharged, or to make provision for, any such lien or charge
                 or to pay any such tax, assessment or governmental charge so
                 long as the validity thereof shall be contested in good faith;
                 and provided further that neither the Company nor any
                 Subsidiary shall be required to pay any such taxes,
                 assessments or charges, if, in the judgment of the Board of
                 Directors of the Company or such Subsidiary, such payment
                 shall no longer be advantageous to the Company or such
                 Subsidiary in the conduct of its business and nonpayment shall
                 not be disadvantageous in any material respect to the
                 Debentureholders.

                 (b)  Subject to the other provisions of this Indenture, the
                 Company will, and will cause each Subsidiary to, maintain its
                 corporate existence and right to carry on its business and
                 duly procure all necessary renewals and extensions thereof and
                 use its best efforts to maintain, preserve and renew all such
                 rights, powers, privileges and franchises; provided, however,
                 that nothing herein contained shall be construed to prevent
                 the Company or Subsidiary from ceasing or omitting to exercise
                 any right, power, privilege or franchise (including, in the
                 case of a Subsidiary, the corporate existence thereof) which
                 in the judgment of the Board of Directors of the Company or of
                 such Subsidiary should not be exercised and which is not
                 advantageous in any material respect to the Debentureholders.

                 (c)      The Company will, and will cause each Subsidiary to,
                 keep and maintain all buildings, plants and other property
                 owned or leased by it in such good condition, repair and
                 working order and supplied with all such necessary equipment
                 as in the judgment of the Company may be necessary, so that
                 the business carried on in connection therewith may be
                 properly and advantageously





                                       37

                 conducted at all times; provided, however, that nothing in
                 this Section 6.06 shall prevent the Company or a Subsidiary
                 from selling, abandoning or otherwise disposing of any
                 building, plant or property whenever in the opinion of the
                 Company the retention thereof is inadvisable or not necessary
                 to the business of the Company or such Subsidiary.

                 (d)      The Company will insure and keep insured, and will
                 cause each Subsidiary to insure and keep insured, to a
                 reasonable amount with reputable insurance companies, to the
                 extent such insurance is reasonably available, so much of
                 their respective properties as companies engaged in a similar
                 business and to the extent such companies in accordance with
                 good business practice customarily insure properties of a
                 similar character against loss by fire and the extended
                 coverage perils and other hazards.

                 SECTION 6.07.    Annual Review Certificate.  The Company
covenants and agrees to deliver to the Trustee, on or before a date not more
than four months after the end of each fiscal year of the Company ending after
the date hereof, an Officers' Certificate, which shall conform to the
provisions of Section 16.06, stating that a review of the activities of the
Company and of its Subsidiaries during the preceding fiscal year has been made
under the supervision of the signing officers with a view to determining
whether the Company has kept, observed, performed and fulfilled its obligations
under this Indenture, and further stating, as to each such officer signing such
certificate, that to the best of his knowledge the Company has kept, observed,
performed and fulfilled each and every such covenant in this Indenture
contained and is not in default in the performance and observance of any of the
terms, provisions and conditions hereof (or, if the Company shall be in
default, specifying all such defaults and the nature thereof of which he may
have knowledge) and that to the best of his knowledge no event has occurred and
remains in existence by reason of which payments on account of the principal of
or interest on the Debentures is prohibited.

                 SECTION 6.08.    No Lien Created.  This Indenture and the
Debentures do not create a lien, charge, or encumbrance on any property of the
Company or any Subsidiary.

                      DEBENTUREHOLDERS' LISTS AND REPORTS
                         BY THE COMPANY AND THE TRUSTEE

                 SECTION 7.01.    Debentureholders' Lists.  The Company
covenants and agrees that it will furnish or cause to be furnished to the
Trustee not more than 30 or less than 15 calendar days before an Interest

                                       38

times as the Trustee may request in writing, within thirty days after receipt
by the Company of any such request, a list in such form as the Trustee may
reasonably require containing all information in the possession or control of
the Company, and of any paying agents of the Company other than the Trustee, as
to the names and addresses of the holders of Debentures obtained (in the case
of each list other than the first list) since the date as of which the next
previous list, if any, was furnished.  Any such list may be dated as of a date
not more than fifteen days prior to the time such information is furnished or
caused to be furnished, and need not include information received after such
date, but the list need not be furnished if the Trustee is the Debenture
registrar.

                 SECTION 7.02.    Preservation and Disclosure of Lists.

                 (a)      The Trustee shall preserve, in as current a form as
                 is reasonably practicable, all information as to the names and
                 addresses of the holders of Debentures (1) contained in the
                 most recent list furnished to it as provided in Section 7.01
                 and (2) received by it in the capacity of Debenture registrar
                 (if so acting) hereunder.

                 The Trustee may (1) destroy any list furnished to it as
                 provided in Section 7.01 upon receipt of a new list so
                 furnished, (2) destroy any information received by it as
                 paying agent (if so acting) hereunder upon delivering to
                 itself as Trustee, not earlier than forty-five days after an
                 Interest Payment Date, a list containing the names and
                 addresses of the holders of Debentures obtained from such
                 information since the delivery of the next previous list, if
                 any, and (3) destroy any list delivered to itself as Trustee
                 which was compiled from information received by it as paying
                 agent (if so acting) hereunder upon the receipt of a new list
                 so delivered.

                 (b)      In case three or more holders of Debentures
                 (hereinafter referred to as "applicants") apply in writing to
                 the Trustee and furnish to the Trustee reasonable proof that
                 each such applicant has owned a Debenture for a period of at
                 least six months preceding the date of such application, and
                 such application states that the applicants desire to
                 communicate with other holders of Debentures with respect to
                 their rights under this Indenture or under the Debentures and
                 is accompanied by a copy of the form of proxy or other
                 communication which such applicants propose to transmit, then
                 the Trustee shall, within five business days after the receipt
                 of such application, at its election, either





                                       39

                          (1)     afford such applicants access to the
                          information preserved at the time by the Trustee in
                          accordance with the provisions of subsection (a) of
                          this Section 7.02, or

                          (2)     inform such applicants as to the approximate
                          number of holders of Debentures whose names and
                          addresses appear in the information preserved at the
                          time by the Trustee in accordance with the provisions
                          of subsection (a) of this Section 7.02, and as to the
                          approximate cost of mailing to such Debentureholders
                          the form of proxy or other communication, if any,
                          specified in such application.

                 If the Trustee shall elect not to afford such applicants
access to such information, the Trustee shall, upon the written request of such
applicants, mail to each Debentureholder whose name and address appears in the
information preserved at the time by the Trustee in accordance with the
provisions of subsection (a) of this Section 7.02, a copy of the form of proxy
or other communication which is specified in such request, with reasonable
promptness after a tender to the Trustee of the material to be mailed and of
payment, or provision for the payment, of the reasonable expenses of mailing,
unless within five days after such tender the Trustee shall mail to such
applicants and file with the Securities and Exchange Commission, together with
a copy of the material to be mailed, a written statement to the effect that, in
the opinion of the Trustee, such mailing would be contrary to the best
interests of the holders of Debentures or would be in violation of applicable
law.  Such written statement shall specify the basis of such opinion.  If said
Commission, after opportunity for a hearing upon the objections specified in
the written statement so filed, shall enter an order refusing to sustain any of
such objections or if, after the entry of an order sustaining one or more of
such objections, said Commission shall find, after notice and opportunity for
hearing, that all the objections so sustained have been met and shall enter an
order so declaring, the Trustee shall mail copies of such material to all such
Debentureholders with reasonable promptness after the entry of such order and
the renewal of such tender; if no such order is entered by said Commission, the
Trustee shall be relieved of any obligation or duty to such applicants
respecting their application.

                 (c)      Each and every holder of the Debentures, by receiving
                 and holding the same, agrees with the Company and the Trustee
                 that neither the Company nor the Trustee





                                       40
<PAGE>   48
                 nor any paying agent shall be held accountable by reason of
                 the disclosure of any such information as to the names and
                 addresses of the holders of Debentures in accordance with the
                 provisions of subsection (b) of this Section 7.02, regardless
                 of the source from which such information was derived, and
                 that the Trustee shall not be held accountable by reason of
                 mailing any material pursuant to a request made under said
                 subsection (b).

                 SECTION 7.03.    Reports by the Company.

                 (a)      The Company covenants and agrees to file with the
                 Trustee, within fifteen days after the Company is required to
                 file the same with the Securities and Exchange Commission,
                 copies of the annual reports and of the information, documents
                 and other reports (or copies of such portions of any of the
                 foregoing as said Commission may from time to time by rules
                 and regulations prescribe) which the Company may be required
                 to file with said Commission pursuant to Section 13 or Section
                 15(d) of the Securities Exchange Act of 1934; or, if the
                 Company is not required to file information, documents or
                 reports pursuant to either of such sections, then to file with
                 the Trustee and said Commission, in accordance with rules and
                 regulations prescribed from time to time by said Commission,

                 and reports which may be required pursuant to Section 13 of
                 the Securities Exchange Act of 1934 in respect of a security
                 listed and registered on a national securities exchange as may
                 be prescribed from time to time in such rules and regulations.

                 (b)      The Company covenants and agrees to file with the
                 Trustee and the Securities and Exchange Commission, in
                 accordance with the rules and regulations prescribed from time
                 to time by said Commission, any additional information,
                 documents and reports with respect to compliance by the
                 Company with the conditions and covenants provided for in this
                 Indenture as may be required from time to time by such rules
                 and regulations.

                 (c)      The Company covenants and agrees to transmit by mail
                 to all holders of Debentures, as the names and addresses of
                 such holders appear upon the registry books of the Company,
                 within thirty days after the filing thereof with the Trustee,
                 such summaries of any information, documents and reports
                 required to be filed by the Company pursuant to subsections
                 (a) and (b) of this Section 7.03 as may be required by rules
                 and

                 regulations prescribed from time to time by the Securities and
                 Exchange Commission, except insofar as such summaries,
                 documents or reports have previously been furnished to such
                 Debentureholder.

                 (d)      The Company covenants and agrees to transmit by mail

                 SECTION 7.04.    Reports by the Trustee.

                 (a)  If this Indenture has been qualified under the Trust

                          (4)     the property and funds, if any, physically in
                          the possession of the Trustee, as such, on the date
                          of such report; and

                          (5)     any action taken by the Trustee in the
                          performance if its duties under this Indenture which
                          it has not previously reported and which in its
                          opinion materially affects the Debentures, except
                          action in respect of a default, notice of which has
                          been or is to be withheld by it in accordance with
                          the provisions of Section 8.08.


                 (b)      If this Indenture has been qualified under the Trust
                 Indenture Act of 1939, the Trustee shall transmit to the
                 Debentureholders, as hereinafter provided, a brief report with
                 respect to the character and amount of any advances (and if
                 the Trustee elects so to state, the circumstances surrounding
                 the making thereof) made by the Trustee (as such), since the
                 date of the last report transmitted pursuant to the provisions
                 of subsection (a) of this Section 7.04 (or if no such report
                 has yet been so transmitted, since the date of execution of
                 this Indenture), for the reimbursement of which it claims or
                 may claim a lien or charge prior to that of the Debentures on
                 property or funds held or collected by it as Trustee, and
                 which it has not previously reported pursuant to this
                 subsection, except that the Trustee shall not be required (but
                 may elect) to report such advances if such advances remaining
                 unpaid at any time aggregate ten per cent or less of the
                 principal amount of Debentures outstanding at such time, such
                 report to be transmitted within ninety days after such time.


                 (c)      Reports pursuant to this Section 7.04 shall be
                 transmitted by mail to all holders of Debentures, as the names
                 and addresses of such holders appear upon the registry books
                 of the Company.

                 (d)      A copy of any such report shall, at the time of such
                 transmission to Debentureholders, be filed by the Trustee with
                 each stock exchange upon which the Debentures are listed and
                 also with the Securities and Exchange Commission.  The Company
                 will notify the Trustee when the Debentures are listed on any
                 stock exchange.

                  REMEDIES OF THE TRUSTEE AND DEBENTUREHOLDERS
                              ON EVENT OF DEFAULT

following Events of Default shall have occurred and be continuing, that is to
say:

                 (a)      default in the payment of any installment of interest
                 upon any of the Debentures as and when the same shall become
                 due and payable, whether or not such payment is prohibited by
                 the provisions of Article Four, and continuance of such
                 default for a period of thirty days; or

                 (b)      default in the payment of the principal of any of the
                 Debentures as and when the same shall become due and payable
                 either at maturity, by declaration or otherwise, and in each
                 case whether or not such payment is prohibited by the
                 provisions of Article Four; or

                 (c)      failure on the part of the Company duly to observe or
                 perform any other of its covenants or agreements contained in
                 the Debentures or in this Indenture for a period of sixty days
                 after the date on which written notice of such failure,
                 specifying such default and requiring the same to be remedied,
                 shall have been given to the Company by the Trustee, or to the
                 Company and the Trustee by the holders of at least twenty-five
                 per cent in principal amount of the Debentures at the time
                 outstanding; or

                 (d)      an event of default as defined in any indenture or
                 instrument evidencing or under which the Company has at the
                 date of this Indenture or shall hereafter have outstanding any
                 indebtedness for money borrowed by the Company shall have
                 happened and shall be continuing and such indebtedness shall
                 have been accelerated so that the same shall be or become due
                 and payable prior to the date on which the same would
                 otherwise become due and payable, and such acceleration shall
                 not be contested in good faith by the Company, and such
                 acceleration shall





                                       44
<PAGE>   52
                 not be rescinded or annulled, or such indebtedness shall not
                 have been discharged, or there shall not have been deposited
                 in trust a sum of money sufficient to discharge in full such
                 indebtedness, within ten days after written notice of such
                 acceleration to the Company from the Trustee or to the Company
                 and the Trustee from the holders of not less than twenty-five
                 per cent in aggregate principal amount of the Debentures then
                 outstanding hereunder; provided, however, that if such event
                 of default under such indenture or instrument shall be
                 remedied or cured by the Company or be waived by the holders
                 of such indebtedness in any manner authorized by such
                 indenture or instrument or shall otherwise cease to exist,
                 then the Event of Default hereunder by reason thereof shall be
                 deemed likewise to have been thereupon remedied, cured or
                 waived without further action upon the part of either the
                 Trustee or any of the Debentureholders; and provided further
                 that the Trustee, subject to Section 9.01, shall not be
                 charged with knowledge of any such default unless written
                 notice of such default shall have been given to the Trustee by
                 the Company, by the Trustee then acting under any indenture or
                 other instrument under which such default shall have occurred,
                 or by the holders of at least five per cent in aggregate
                 principal amount of the Debentures at the time outstanding; or

                 (e)      the entry of a decree or order for relief by a court
                 having jurisdiction in the premises in respect of the Company
                 in an involuntary case under the Federal Bankruptcy Code or
                 any other applicable federal or state bankruptcy, insolvency
                 or other similar law now or hereafter in effect, or appointing
                 a receiver, liquidator, assignee, trustee, sequestrator or
                 other similar official of the Company or of any substantial
                 part of its property, or ordering the winding up or
                 liquidation of its affairs, and the continuance of any such
                 decree or order unstayed and in effect for a period of sixty
                 consecutive days; or

                 (f)      the commencement by the Company of a voluntary case
                 under the Federal Bankruptcy Code or any other applicable
                 federal or state bankruptcy, insolvency or other similar law
                 now or hereafter in effect, or the consent by the Company to
                 the entry of an order for relief in an involuntary case under
                 any such law, or the consent by the Company to the appointment
                 of or taking possession by a receiver, liquidator, assignee,
                 trustee, sequestrator or other similar official of the Company
                 or of any substantial part of its property, or the making

                 by the Company of an assignment for the benefit of creditors;

then and in each and every such case, unless the principal of all of the
Debentures shall have already become due and payable, either the Trustee or the
holders of not less than twenty-five per cent in aggregate principal amount of
the Debentures then outstanding hereunder, by notice in writing to the Company
(and to the Trustee if given by Debentureholders), may declare the principal of
all the Debentures to be due and payable immediately, and upon any such
declaration the same shall become and shall be immediately due and payable,
notwithstanding anything to the contrary contained in this Indenture or in the
Debentures.  This provision, however, is subject to the condition that if at
any time after the principal of the Debentures shall have been so declared due
and payable, and before any judgment or decree for the payment of the monies
due shall have been obtained or entered as hereinafter provided, the Company
shall pay or shall deposit with the Trustee a sum sufficient to pay all matured
installments of interest upon all of the Debentures and the principal of any
and all Debentures which shall have become due otherwise than by acceleration
(with interest on such principal and, to the extent that payment of such
interest is enforceable under applicable law, on overdue installments of
interest, at the rate borne by the Debentures, through the day preceding the
date of such payment or deposit) and such amount as shall be sufficient to
cover reasonable compensation to the Trustee, its agents, attorneys and
counsel, and all other expenses and liabilities incurred and all advances made
by the Trustee, except as the result of its negligence or bad faith, and any
and all defaults under this Indenture, other than the nonpayment of principal
and accrued interest on Debentures which shall have become due by acceleration,
shall have been remedied -- then and in every such case the holders of a
majority in aggregate principal amount of the Debentures then outstanding, by
written notice to the Company and to the Trustee, may waive all defaults and
rescind and annul such declaration and its consequences; but no such waiver or
rescission and annulment shall extend to or shall affect any subsequent
default, or shall impair any right consequent thereon.

                 In case the Trustee shall have proceeded to enforce any right
under this Indenture and such proceedings shall have been discontinued or
abandoned because of such rescission or annulment or for any other reason or
shall have been determined adversely to the Trustee, then and in every case,
subject to any determination in such proceeding, the Company, the Trustee and
the Debentureholders shall be restored respectively to their several positions
and rights hereunder, and thereafter all rights, remedies and powers of the
Company and the Trustee shall continue as though no such proceeding had been
taken.

                 SECTION 8.02.    Payment of Debentures on Default; Suit
Therefor.  The Company covenants that (1) in case default shall be made in the
payment of any installment of interest upon any of the Debentures as and when
the same shall become due and payable, and such default shall have continued
for a period of thirty days, or (2) in case default shall be made in the
payment of the principal of any of the Debentures as and when the same shall
have become due and payable, whether at maturity of the Debentures or upon
redemption or by declaration or otherwise -- then, upon demand of the Trustee,
the Company will pay to the Trustee, for the benefit of the holders of the
Debentures, the whole amount that then shall have become due and payable on all
such Debentures for principal or interest, or both, as the case may be, with
interest upon the overdue principal and (to the extent that payment of such
interest is enforceable under applicable law) upon overdue installments of
interest at the rate borne by the Debentures, and, in addition thereto, such
further amount as shall be sufficient to cover the costs and expenses of
collection, including a reasonable compensation to the Trustee, its agents,
attorneys, and counsel, and any expenses or liabilities incurred by the Trustee
hereunder other than through its negligence or bad faith.

                 In case the Company shall fail forthwith to pay such amounts
upon such demand, the Trustee, in its own name and as trustee of an express
trust, shall then be entitled and empowered to institute any actions or
proceedings at law or in equity for the collection of the sums so due and
unpaid, and may prosecute any such action or proceeding to judgment or final
decree, and may enforce any such judgment or final decree against the Company
or any other obligor on the Debentures and collect in the manner provided by
law out of the property of the Company or any other obligor on the Debentures
wherever situated the monies adjudged or decreed to be payable.

                 In case there shall be pending any receivership, insolvency,
liquidation, bankruptcy, reorganization, arrangement, adjustment, composition
or other judicial proceeding relative to the Company or any other obligor on
the Debentures, its or their creditors, as such, or its or their property, the
Trustee, irrespective of whether the principal of the Debentures shall then be
due and payable as therein expressed or by declaration or otherwise and
irrespective of whether the Trustee shall have made any demand pursuant to the
provisions of this Section 8.02, shall be entitled and empowered, by the
intervention in such proceedings or otherwise, to file and prove a claim or
claims for the whole amount of principal and interest owing and unpaid in
respect of the Debentures, and, in case of any judicial proceedings, to file
such proofs of claim and other papers or documents as may be necessary or
advisable in order to have the claims of the Trustee and of the
Debentureholders allowed in such judicial proceedings relative to the Company
or any other obligor on the Debentures,





                                       47
<PAGE>   55
its or their creditors, or its or their property, and to collect and receive
any monies or other property payable or deliverable on any such claims, and to
distribute the same after the deduction of its charges and expenses; and any
receiver, assignee or trustee in bankruptcy or reorganization is hereby
authorized by each of the Debentureholders to make such payments to the
Trustee, and, in the event that the Trustee shall consent to the making of such
payments directly to the Debentureholders, to pay to the Trustee any amount due
it for compensation and expenses, including counsel fees incurred by it up to
the date of such distribution.  To the extent that such payment of reasonable
compensation, expenses and counsel fees out of the estate in any such
proceedings shall be denied for any reason, payment of the same shall be
secured by a lien on, and shall be paid out of, any and all distributions,
dividends, monies, securities and other property which the holders of the
Debentures may be entitled to receive in such proceedings, whether in
liquidation or under any plan of reorganization or arrangement or otherwise.

                 All rights of action and of asserting claims under this
Indenture, or under any of the Debentures, may be enforced by the Trustee
without the possession of any of the Debentures, or the production thereof on
any trial or other proceeding relative thereto, and any such suit or proceeding
instituted by the Trustee shall be bought in its own name as trustee of an
express trust, and any recovery of judgment shall be for the ratable benefit of
the holders of the Debentures, subject to the provisions of Article Four.

                 SECTION 8.03.  Application of Monies Collected by Trustee.
Subject to the provisions of Article Four, any monies collected by the Trustee
pursuant to Section 8.02 shall be applied in the order following, at the date
or dates fixed by the Trustee for the distribution of such monies, upon
presentation of the several Debentures, and stamping thereon the payment, if
only partially paid, and upon surrender thereof if fully paid:

                 First:  To the payment of costs and expenses of collection and
                 reasonable compensation to the Trustee, its agents, attorneys
                 and counsel, and of all other expenses and liabilities
                 incurred, and all advances made, by the Trustee except as a
                 result of its negligence or bad faith;

                 Second:  In case the principal of the outstanding Debentures
                 shall not have become due and be unpaid, to the payment of
                 interest on the Debentures, in the order of the maturity of
                 the installments of such interest, with interest (to the
                 extent that such interest has been collected by the Trustee)
                 upon the overdue installments of interest at the same rate as
                 the rate borne by the





                                       48
<PAGE>   56
                 Debentures, such payments to be made ratably to the persons
                 entitled thereto, without discrimination or preference; and

                 Third:  In case the principal of the outstanding Debentures
                 shall have become due, by declaration or otherwise, to the
                 payment of the whole amount then owing and unpaid upon the
                 Debentures for principal and interest, with interest on the
                 overdue principal; and (to the extent that such interest has
                 been collected by the Trustee) upon overdue installments of
                 interest at the rate borne by the Debentures; and in case such
                 monies shall be insufficient to pay in full the whole amounts
                 so due and unpaid upon the Debentures, then to the payment of
                 such principal and interest without preference or priority of
                 principal over interest, or of interest over principal, or of
                 any installment of interest over any other installment of
                 interest, or of any Debenture over any other Debenture,
                 ratably to the aggregate of such principal and accrued and
                 unpaid interest; and

                 Fourth:  To the payment of the remainder, if any, to the
                 Company, its successors or assigns, or to whomsoever may be
                 lawfully entitled to receive the same, or as a court of
                 competent jurisdiction may direct.

                 SECTION 8.04.    Proceedings by Debentureholders.  No holder
of any Debenture shall have any right by virtue of or by availing of any
provision of this Indenture to institute any suit, action or proceeding in
equity or at law upon or under or with respect to this Indenture or for the
appointment of a receiver or trustee, or for any other remedy hereunder, unless
such holder previously shall have given to the Trustee written notice of
default and of the continuance thereof, as hereinbefore provided, and unless
also (i) the holders of not less than twenty-five per cent in aggregate
principal amount of the Debentures then outstanding shall have made written
request upon the Trustee to institute such action, suit or proceeding in its
own name as Trustee hereunder and (ii) the holders making such request shall
have offered to the Trustee such reasonable indemnity as it may require against
the costs, expenses and liabilities to be incurred therein or thereby, (iii)
the Trustee for sixty days after its receipt of such notice, request and offer
of indemnity shall have neglected or refused to institute any such action, suit
or proceeding, and (iv) no direction inconsistent with such written request
shall have been given to the Trustee during such sixty day period by the
holders of a majority in principal amount of the Debentures then outstanding;
it being understood and intended,and being expressly covenanted by the taker
and holder of every Debenture with every other taker and holder and the
Trustee, that





                                       49
<PAGE>   57
no one or more holders of Debentures shall have any right in any manner
whatever by virtue of or by availing of any provision of this Indenture to
affect, disturb or prejudice the rights of any other holder of such Debentures,
or to obtain or seek to obtain priority over or preference to any other such
holder, or to enforce any right under this Indenture, except in the manner
herein provided and for the equal, ratable and common benefit of all holders of
Debentures.

                 Notwithstanding any other provisions in this Indenture, but
subject to the provisions of Article Four, the right of any holder of any
Debenture to receive payment of the principal and interest on such Debenture,
on or after the respective due dates expressed in such Debenture, or to
institute suit for the enforcement of any such payment on or after such
respective dates against the Company, shall not be impaired or affected without
the consent of such holder; provided, however, that the provisions of this
Section 8.04 are subject to the provisions of Article Four.

                 SECTION 8.05.    Proceedings by Trustee.  In case of an Event
of Default hereunder the Trustee may in its discretion proceed to protect and
enforce the rights vested in it by this Indenture by such appropriate judicial
proceedings as the Trustee shall deem most effectual to protect and enforce any
of such rights, either by suit in equity or by action at law or by proceeding
in bankruptcy or otherwise, whether for the specific enforcement of any
covenant or agreement contained in this Indenture or in aid of the exercise of
any power granted in this Indenture, or to enforce any other legal or equitable
right vested in the Trustee by this Indenture or by law.

                 SECTION 8.06.    Remedies Cumulative and Continuing.  All
powers and remedies given by this Article Eight to the Trustee or to the
Debentureholders shall, to the extent permitted by law, be deemed cumulative
and not exclusive of any thereof or of any other powers and remedies available
to the Trustee or the holders of the Debentures by judicial proceedings or
otherwise to enforce the performance or observance of the covenants and
agreements contained in this Indenture, and no delay or omission of the Trustee
or of any holder of any of the Debentures to exercise any right or power
accruing upon any default occurring and continuing as aforesaid shall impair
any such right or power, or shall be construed to be a waiver of any such
default or an acquiescence therein; and, subject to the provisions by Section
8.04, every power and remedy given by this Article Eight or by law to the
Trustee or to Debentureholders may be exercised from time to time, and as often
as shall be deemed expedient, by the Trustee or by the Debentureholders.

                 SECTION 8.07.  Direction of Proceedings and Waiver of Defaults
by Majority of Debentureholders.  The holders of a





                                       50
<PAGE>   58
majority in aggregate principal amount of the Debentures at the time
outstanding determined subject to the provisions of Section 10.04 shall have
the right to direct the time, method and place of conducting any proceeding for
any remedy available to the Trustee, or exercising any trust or power conferred
on the Trustee; provided, however, that the Trustee, subject to the provisions
of Section 9.01, shall have the right to decline to follow any such direction
if the Trustee in good faith shall, by a Responsible Officer or Officers of the
Trustee, determine that the proceeding so directed would involve it in a
personal liability or would be in conflict with any rule of law or provision of
this Indenture; and provided further, that nothing in this Indenture contained
shall impair the right of the Trustee in its discretion to take any action
deemed proper by the Trustee and which is not inconsistent with such direction
by Debentureholders.  Prior to any declaration accelerating the maturity of the
Debentures, the holders of a majority in aggregate principal amount of the
Debentures at the time outstanding determined subject to the provisions of
Section 10.04 may on behalf of the holders of all of the Debentures waive any
past default or Event of Default hereunder and its consequences, except by
default in the payment of interest on the principal of any of the Debentures or
in respect of a covenant or provision hereof which under Article Twelve cannot
be modified or amended without the consent of the holder of each Debenture
affected.  Upon any such waiver, the Company, the Trustee and the holders of
the Debentures shall be restored to their former positions and rights
hereunder, respectively; but no such waiver shall extend to any subsequent or
other default or Event of Default or impair any right consequent thereon.
Whenever any default or Event of Default hereunder shall have been waived as
permitted by this Section 8.07, said default or Event of Default shall for all
purposes of the Debentures and this Indenture be deemed to have been cured and
to be not continuing.

                 SECTION 8.08.    Notice of Defaults.  The Trustee shall,
within ninety days after the occurrence of a default, mail to all holders of
Debentures, as the names and addresses of such holders appear upon the registry
books of the Company, notice of all defaults known to the Trustee, unless such
defaults shall have been cured or waived before the giving of such notice (the
term "defaults" for the purposes of this Section 8.08 being hereby defined to
be the events specified in clauses (a), (b), (c), (d), (e) and (f) of Section
8.01, not including any periods of grace provided for in said clauses (a), (c),
(d) and (e) and irrespective of the giving of written notice provided for in
said clauses (c) and (d)); provided, that, except in the case of default in the
payment of the principal of or interest on any of the Debentures, the Trustee
shall be protected in withholding such notice if and so long as the board of
directors, the executive committee, or a trust committee of directors and/or
Responsible





                                       51
<PAGE>   59
Officers of the Trustee in good faith determine that the withholding of such
notice is in the interests of the Debentureholders.

                 SECTION 8.09.    Undertaking to Pay Costs.  All parties to
this Indenture agree, and each holder of any Debenture by his acceptance
thereof shall be deemed to have agreed, that any court may in its discretion
require, in any suit for the enforcement of any right or remedy under this
Indenture, or in any suit against the Trustee for any action taken or omitted
by it as Trustee, the filing by any party litigant in such suit of an
undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party litigant; but the
provisions of this Section 8.09 shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Debentureholder, or group of
Debentureholders, holding in the aggregate more than ten per cent in aggregate
principal amount of the Debentures outstanding, or to any suit instituted by
any Debentureholder for the enforcement of the payment of the principal of or
interest on any Debenture against the Company on or after the due date
expressed in such Debenture.

                 SECTION 8.10.    Enforcement of Conversion Rights.  Anything
in this Indenture to the contrary notwithstanding, the holder of any Debenture,
without reference to and without the consent of either the Trustee or the
holder of any other Debenture, in his own behalf and for his own benefit may
enforce, and may institute and maintain any proceedings suitable to enforce,
his right to convert his Debenture into 1994-1 Series Stock as provided in
Article Five.

                 SECTION 8.11.    Waiver of Stay, Extension, or Usury Laws.
The Company covenants (to the extent that it may lawfully do so) that it will
not at any time insist upon, or plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay, extension, or usury law wherever
enacted, now or at any time hereafter in force, which may affect the covenants
or the performance of this Indenture; and the Company (to the extent that it
may lawfully do so) hereby expressly waives all benefit or advantage of any
such law, and covenants that it will not hinder, delay, or impede the execution
of any power herein granted to the Trustee, but will suffer and permit the
execution of every such power as though no such law had been enacted.



                                  ARTICLE NINE

                             CONCERNING THE TRUSTEE

<PAGE>   60
                 SECTION 9.01.    Duties and Liabilities of Trustee.  The
Trustee prior to the occurrence of an Event of Default and after the curing of
all Events of Default which may have occurred, undertakes to perform such
duties and only such duties as are specifically set forth in this Indenture.
No implied covenants or obligations shall be read into this Indenture against
the Trustee.  In case an Event of Default has occurred (which has not been
cured) the Trustee shall exercise such of the rights and powers invested in it
by this Indenture, and use the same degree of care and skill in their exercise,
as a prudent man would exercise or use under the circumstances in the conduct
of his own affairs.

                 No provisions of this Indenture shall be construed to relieve
the Trustee from liability for its own negligent action, its own negligent
failure to act, or its own willful misconduct of its own affairs, except that

                 (a)      prior to the occurrence of an Event of Default and
                 after the curing of all Events of Default which may have
                 occurred:

                          (1)     the duties and obligations of the Trustee
                          shall be determined solely by the express provisions
                          of this Indenture, and the Trustee shall not be
                          liable except for the performance of such duties and
                          obligations as are specifically set forth in this
                          Indenture, and no implied covenants or obligations
                          shall be read into this Indenture against the
                          Trustee; and

                          (2)     in the absence of bad faith on the part of
                          the Trustee, the Trustee may conclusively rely, as to
                          the truth of the statements and the correctness of
                          the opinions expressed therein, upon any certificates
                          or opinions furnished to the Trustee and conforming
                          to the requirements of this Indenture; but in the
                          case of any such certificates or opinions which by
                          any provision hereof are specifically required to be
                          furnished to the Trustee, the Trustee shall be under
                          a duty to examine the same to determine whether or
                          not they conform to the requirements of this
                          Indenture;

                 (b)  The Trustee shall not be liable for any error of judgment
                 made in good faith by a Responsible Officer or Officers of the
                 Trustee, unless it shall be proved that the Trustee was
                 negligent in ascertaining the pertinent facts; and

                 (c)      the Trustee shall not be liable with respect to any
                 action taken or omitted to be taken by it in good faith





                                       53
<PAGE>   61
                 in accordance with the direction of the holders of not less
                 than a majority in principal amount of the Debentures at the
                 time outstanding determined as provided in Section 10.04
                 relating to the time, method and place of conducting any
                 proceeding for any remedy available to the Trustee, or
                 exercising any trust or power conferred upon the Trustee,
                 under this Indenture.

                 None of the provisions contained in this Indenture shall
require the Trustee to expend or risk its own funds or otherwise incur personal
financial liability in the performance of any of its duties or in the exercise
of any of its right or powers, if there is reasonable ground for believing that
the repayment of such funds or liability is not reasonably assured to it.

                 SECTION 9.02.  Reliance on Documents and Counsel.  Except as
otherwise provided in Section 9.01:

                 (a)      The Trustee may rely and shall be protected in acting
                 or refraining from acting upon any resolution, certificate,
                 statement, instrument, opinion, report, notice, request,
                 consent, order, bond, debenture, coupon, or other paper or
                 document believed by it to be genuine and to have been signed
                 or presented by the proper party or parties;

                 (b)      Any request, direction, order or demand of the
                 Company mentioned herein shall be sufficiently evidenced by an
                 Officers' Certificate (unless other evidence in respect
                 thereof be herein specifically prescribed); and any resolution
                 of the Board of Directors of the Company may be evidenced to
                 the Trustee by a copy thereof certified by the Secretary or an
                 Assistant Secretary of the Company;

                 (c)      The Trustee may consult with counsel and any written
                 advice or Opinion of Counsel shall be full and complete
                 authorization and protection in respect of any action taken or
                 omitted by it hereunder in good faith and in accordance with
                 such advice or Opinion of Counsel;

                 (d)      The Trustee shall be under no obligation to exercise
                 any of the rights or powers vested in it by this Indenture at
                 the request, order or direction of any of the
                 Debentureholders, pursuant to the provisions of this
                 Indenture, unless such Debentureholders shall have offered to
                 the Trustee reasonable security or indemnity against the
                 costs, expenses and liabilities which may be incurred therein
                 or thereby;





                                       54
<PAGE>   62
                 (e)      The Trustee shall not be liable for any action taken
                 or omitted by it in good faith and believed by it to be
                 authorized or within the discretion or rights or powers
                 conferred upon it by this Indenture;

                 (f)      Prior to the occurrence of an Event of Default
                 hereunder and after the curing of all Events of Default, the
                 Trustee shall not be bound to make any investigation into the
                 facts or matters stated in any resolution, certificate,
                 statement, instrument, opinion, report, notice, request,
                 consent, order, approval, appraisal, bond, debenture, coupon
                 or other paper or document, unless requested in writing so to
                 do by the holders of a majority in aggregate principal amount
                 of the Debentures then outstanding determined subject to the
                 provisions of Section 10.04; provided, that if the payment
                 within a reasonable time to the Trustee of the costs, expenses
                 or liabilities likely to be incurred by it in the making of
                 such investigation is not, in the opinion of the Trustee,
                 reasonably assured to the Trustee by the security afforded to
                 it by the terms of this Indenture, the Trustee may require
                 reasonable indemnity against such expense or liability as a
                 condition to so proceeding; the reasonable expense of every
                 such examination shall be paid by the Company or, if paid by
                 the Trustee, shall be repaid by the Company upon demand; and

                 (g)      The Trustee may execute any of the trusts or powers
                 hereunder or perform any duties hereunder either directly or
                 by or through agents or attorneys.  The Trustee shall not be
                 responsible for any misconduct or negligence on the part of
                 any agent or attorney appointed with due care by it hereunder.

             SECTION 9.03.  No Responsibility for Recitals or Certain Other
Matters.  The recitals contained herein and in the Debentures (except in the
Trustee's certificate of authentication) shall be taken as the statements of
the Company, and the Trustee assumes no responsibility for the correctness of
the same.  The Trustee makes no representations as to the validity or
sufficiency of this Indenture or of the Debentures.  The Trustee shall not be
accountable for the use or application by the Company of any Debentures or the
proceeds of any Debenture.

             SECTION 9.04.  Trustee, Paying Agent, Conversion Agent or
Registrar May Own Debentures.  The Trustee or any paying agent, conversion
agent or Debenture registrar, in its individual or any other capacity, may
become the owner or pledgee of Debentures with the same rights it would have if
it were not Trustee, paying agent, conversion agent or Debenture registrar.

<PAGE>   63
             SECTION 9.05.  Monies to be Held in Trust.  Subject to the
provisions of Article Four and Section 14.04 hereof, all monies received by the
Trustee shall, until used or applied as herein provided, be held in trust for
the purposes for which they were received.  The Trustee shall be under no
liability for interest on any monies received by it hereunder except such as it
may agree with the Company to pay thereon.  Money held by the Trustee in trust
hereunder need not be segregated from other funds except to the extent required
by law.  So long as no Event of Default shall have occurred and be continuing,
all interest allowed on any such monies shall be paid from time to time upon
the written order of the Company, signed by its President or any Vice President
or its Treasurer or an Assistant Treasurer.

             SECTION 9.06.  Compensation and Expenses of Trustee.  The Company
covenants and agrees to pay to the Trustee from time to time, and the Trustee
shall be entitled to, reasonable compensation (which shall not be limited by
any provision of law in regard to the compensation of a trustee of an express
trust), and the Company will pay or reimburse the Trustee upon its request for
all reasonable expenses, disbursements and advances incurred or made by the
Trustee in accordance with any of the provisions of this Indenture (including
the reasonable compensation and the expense and disbursement of its counsel and
of all persons not regularly in its employ) except any such expenses,
disbursements or advance as may arise from its negligence or bad faith.  The
Company also covenants to indemnify the Trustee for, and to hold it harmless
against, any loss, liability or expense incurred without negligence or bad
faith on the part of the Trustee and arising out of or in connection with the
acceptance or administration of this trust, including the costs and expenses of
defending itself against any claim of liability in the premises.  The
obligations of the Company under this Section 9.06 to compensate the Trustee
and to pay or reimburse the Trustee for expenses, disbursements and advances
shall constitute additional indebtedness hereunder, and such additional
indebtedness shall be secured by a lien prior to that of the Debentures upon
all property and funds held or collected by the Trustee as such, except funds
held in trust for the payment of principal of or interest on Debentures.

             SECTION 9.07.  Officers' Certificate as Evidence.  Except as
otherwise provided in Section 9.01, whenever in the administration of the
provisions of this Indenture the Trustee shall deem it necessary or desirable
that a matter be proved or established prior to taking, suffering, or omitting
any action hereunder, such matter (unless other evidence in respect thereof be
herein specifically prescribed) may, in the absence of negligence or bad faith
on the part of the Trustee, be deemed to be conclusively proved and established
by an Officers' Certificate delivered to the Trustee, and such Certificate, in
the absence of





                                       56
<PAGE>   64
negligence or bad faith on the part of the Trustee, shall be full warrant to
the Trustee for any action taken or omitted by it under the provisions of this
Indenture upon the faith thereof.


             SECTION 9.08.  Conflicting Interest of the Trustee.

             (a)    If the Trustee has or shall acquire any conflicting
             interest, as defined in this Section 9.08, it shall, within ninety
             days after ascertaining that it has such conflicting interest,
             either eliminate such conflicting interest, or resign in the
             manner and with the effect specified in Section 9.10.

             (b)    In the event that the Trustee shall fail to comply with the
             provisions of subsection (a) of this Section 9.08, the Trustee
             shall, within ten days after the expiration of such ninety-day
             period, transmit notice of such failure by mail to all holders of
             Debentures, as the names and addresses of such holders appear upon
             the registration books of the Company.

             (c)    For the purposes of this Section 9.08, the Trustee shall be
             deemed to have a conflicting interest if

                    (1) the Trustee is trustee under another indenture under
                    which any other securities, or certificates of interest or
                    participation in any other securities, of the Company are
                    outstanding, unless such other indenture is a collateral
                    trust indenture under which the only collateral consists of
                    Debentures issued under this Indenture; provided, however,
                    that there shall be excluded from the operation of this
                    paragraph:  (A) the Indenture dated as of August 17, 1984

                    the Indenture dated as of November 15, 1991, with Deposit
                    Guaranty National Bank as Trustee, under which the
                    Company's 1991-2 Series Convertible Subordinated Debentures
                    are outstanding, (N) the Indenture dated as of November 13,
                    1992, with Deposit Guaranty National Bank as Trustee, under
                    which the Company's 1992-1 Series Convertible Subordinated
                    Debentures are outstanding, (O) any other indenture or
                    indentures under which other securities, or certificates of
                    interest or participation in other securities, of the
                    Company are outstanding if (i) this Indenture and such
                    other indenture or indentures are wholly unsecured and such
                    other indenture or indentures are hereafter qualified under
                    the Trust Indenture Act of 1939, unless the Securities and
                    Exchange Commission shall have found and declared by order
                    pursuant to subsection (b) of Section 305 or subsection (c)
                    of Section 307 of the Trust Indenture Act of 1939 that
                    differences exist between the provisions of this Indenture
                    and the provisions of such other indenture or indentures
                    which are so likely to involve a material conflict of
                    interest as to make it necessary in the public interest or
                    for the protection of investors to disqualify the Trustee
                    from acting as

                    such under this Indenture and such other indenture or
                    indentures, or (ii) the Company shall have sustained the
                    burden of proving, on application to the Securities and
                    Exchange Commission and after opportunity for hearing
                    thereon, that the trusteeship under this Indenture and such
                    other indenture is not so likely to involve a material
                    conflict of interest as to make it necessary in the public
                    interest or for the protection of investors to disqualify
                    the Trustee from acting as such under one of such
                    indentures, or (iii) such other indenture or indentures
                    contain substantially the same terms as this Indenture and
                    such other indenture or indentures and this Indenture are
                    exempt from qualification under the Trust Indenture Act of
                    1939.

                    (2)    The Trustee or any of its directors or executive
                    officers is an obligor upon the Debentures issued under
                    this Indenture or an underwriter for the Company;

                    (3)    the Trustee directly or indirectly controls or is
                    directly or indirectly controlled by or is under direct or
                    indirect common control with the Company or an underwriter
                    for the Company;

                    (4)    the Trustee or any of its directors or executive
                    officers is a director, officer, partner, employee,
                    appointee, or representative of the Company, or of an
                    underwriter (other than the Trustee itself) for the Company
                    who is currently engaged in the business of underwriting,
                    except that (A) one individual may be a director and/or an
                    executive officer of the Trustee and a director and/or an
                    executive officer of the Company, but may not be at the
                    same time an executive officer of both the Trustee and the
                    Company; (B) if and so long as the number of directors of
                    the Trustee in office is more than nine, one additional
                    individual may be a director and/or an executive officer of
                    the Trustee and a director of the Company; and (C) the
                    Trustee may be designated by the Company or by an
                    underwriter for the Company to act in the capacity of
                    transfer agent, registrar, custodian, paying agent, fiscal
                    agent, escrow agent, or depositary, or in any other similar
                    capacity, or, subject to the provisions of paragraph (1) of
                    this subsection (c), to act as trustee whether under an
                    indenture or otherwise;

                    (5)    ten per cent or more of the voting securities of
                    Trustee is beneficially owned either by the Company or by
                    any director, partner, or executive officer

                    thereof, or twenty per cent or more of such voting
                    securities is beneficially owned, collectively, by any two
                    or more of such persons; or ten per cent or more of the
                    voting securities of the Trustee is beneficially owned

                    director, partner, or executive officer thereof, or is
                    beneficially owned collectively, by any two or more such
                    persons;

                    (6)    the Trustee is the beneficial owner of, or holds
                    collateral security for an obligation which is in default,
                    (A) five per cent or more of the voting securities, or ten
                    per cent or more of any other class of security, of the
                    Company, not including the Debentures issued under this
                    Indenture and securities issued under any other indenture
                    under which the Trustee is also trustee, or (B) ten per
                    cent or more of any class of security of an underwriter for
                    the Company;

                    (7)    the Trustee is the beneficial owner of, or holds
                    collateral security for an obligation which is in default,
                    five per cent or more of the voting securities of any
                    person who, to the knowledge of the Trustee, owns ten per
                    cent or more of the voting securities of, or controls
                    directly or indirectly or is under direct or indirect
                    common control with, the Company;

                    (8)    the Trustee is the beneficial owner of, or holds
                    collateral security for an obligation which is in default,
                    ten per cent or more of any class of security of any person
                    who, to the knowledge of the Trustee, owns fifty per cent
                    or more of the voting securities of the Company; or

                    (9)    the Trustee owns on May 15 in any calendar year, in
                    the capacity of executor, administrator, testamentary or
                    inter vivos trustee, guardian, committee or conservator, or
                    in any other similar capacity, an aggregate of twenty-five
                    per cent or more of the voting securities, or of any class
                    of security, of any person, the beneficial ownership of a
                    specified percentage of which would have constituted a
                    conflicting interest under paragraph (6), (7) or (8) of
                    this subsection (c).  As to any such securities of which
                    the Trustee acquired ownership through becoming executor,
                    administrator or testamentary trustee of an estate which
                    included them, the provisions of the preceding sentence
                    shall not apply for a period of two years from the date of
                    such acquisition, to the extent





                                       60

                    that such securities included in such estate do not exceed
                    twenty-five per cent of such voting securities or
                    twenty-five per cent of any such class of security.
                    Promptly after May 15 in each calendar year, the Trustee
                    shall make a check of its holdings of such securities in
                    any of the above-mentioned capacities as of such May 15.
                    If the Company fails to make payment in full of principal
                    of or interest on any of the Debentures when and as the
                    same become due and payable, and such failure continues for
                    thirty days thereafter, the Trustee shall make a prompt
                    check of its holdings of such securities in any of the
                    above-mentioned capacities as of the date of the expiration
                    of such thirty-day period, and after such date,
                    notwithstanding the foregoing provisions of this paragraph
                    (9), all such securities so held by the Trustee, with sole
                    or joint control over such securities vested in it, shall,
                    but only so long as such failure shall continue, be
                    considered as though beneficially owned by the Trustee for
                    the purposes of paragraphs (6), (7) and (8) of this
                    subsection (c).

             The specifications of percentages in paragraphs (5) to (9),
inclusive, of this subsection (c) shall not be construed as indicating that the
ownership of such percentages of the securities of a person is or is not
necessary or sufficient to constitute direct or indirect control for the
purposes of paragraph (3) or (7) of this subsection (c).

             For the purposes of paragraphs (6), (7), (8) and (9) of this
subsection (c) only, (A) the terms "security" and "securities" shall include
only such securities as are generally known as corporate securities, but shall
not include any note or other evidence of indebtedness issued to evidence an
obligation to repay monies lent to a person by one or more banks, trust
companies or banking firms, or any certificate of interest or participation in
any such note or evidence of indebtedness; (B) an obligation shall be deemed to
be in default when a default in payment of principal shall have continued for
thirty days or more and shall not have been cured; and (c) the Trustee shall
not be deemed to be the owner or holder of (i) any security which it holds as
collateral security (as trustee or otherwise) for an obligation which is not in
default as defined in clause (B) above, or (ii) any security which it holds as
collateral security under this Indenture, irrespective of any default
hereunder, or (iii) any security which it holds as agent for collection, or as
custodian, escrow agent, or depositary, or in any similar representative
capacity.

             Except as provided in the next preceding paragraph hereof, the
word "security" or "securities" as used in this Indenture





                                       61

interest in oil, gas or other mineral rights, or, in general, any interest or
instrument commonly known as a "security" or any certificate of interest or

                    participated or has had a participation in the direct or
                    indirect underwriting of any such undertaking, but such

                           by the issuer thereof;

             provided, however, that any voting securities of an issuer shall
             be deemed outstanding if any person other than the issuer is
             entitled to exercise the voting rights thereof.

             (5)    A security shall be deemed to be of the same class as
             another security if both securities confer upon the holder or
             holders thereof substantially the same rights and privileges;
             provided, however, that, in the case of secured evidences of
             indebtedness, all of which are issued under a single indenture,
             differences in the interest rates or maturity dates of various
             series thereof shall not be deemed sufficient to constitute such
             series different classes; and provided further, that, in the case
             of unsecured evidences of indebtedness, differences in the
             interest rates or maturity dates thereof shall not be deemed
             sufficient to constitute them securities of different classes,
             whether or not they are issued under a single indenture.

             SECTION 9.09.  Eligibility of Trustee.    There shall at all times
be a Trustee hereunder which shall at all times be a corporation organized and
doing business under the laws of the United States or any State or Territory
thereof or of the District of Columbia authorized under such laws to exercise
corporate trust powers, having a combined capital and surplus of at least
$10,000,000, subject to supervision or examination by Federal, State,
Territorial, or District of Columbia authority.  If such corporation publishes
reports of condition at least annually, pursuant to law or to the requirements
of the aforesaid supervising or examining authority, then for the purposes of
this Section 9.09, the combined capital and surplus of such corporation shall
be deemed to be its combined capital and surplus as set forth in its most
recent report of condition so published.  In case at any time the Trustee shall
cease to be eligible in accordance with the provisions of this Section 9.09,
the Trustee shall resign immediately in the manner and with the effect
specified in Section 9.10.

             (a)    The Trustee may at any time resign by giving written notice
             of such resignation to the Company and by mailing notice thereof
             to the holders of the Debentures at their addresses as they shall
             appear on the registry books of the Company.  Upon receiving such
             notice of resignation, the Company shall promptly appoint a
             successor trustee by written instrument, in duplicate, executed by
             order of the Board of Directors of the Company, one copy of which
             instrument shall be delivered to the resigning Trustee and one
             copy to the successor trustee.  If no successor trustee shall have
             been so appointed and have accepted appointment within sixty days
             after the giving of such notice of resignation, the resigning
             Trustee may petition any court of competent jurisdiction for the
             appointment of a successor trustee, or any Debentureholder who has
             been a bona fide holder of a Debenture, or Debentures for at least
             six months may, subject to the provisions of Section 8.09, on
             behalf of himself and all other similarly situated, petition any
             such court for the appointment of a successor trustee.  Such court
             may thereupon, after such notice, if any, as it may deem proper
             and prescribe, appoint a successor trustee.

             (b)    In case at any time any of the following shall occur:

                    (1)    the Trustee shall fail to comply with the provisions
                    of subsection (a) of Section 9.08 after written request
                    therefor by the Company or by any Debentureholder who has
                    been a bona fide holder of a Debenture or Debentures for at
                    least six months, or

                    (2)    the Trustee shall cease to be eligible in accordance
                    with the provisions of Section 9.09 and shall fail to
                    resign after written request therefor by the Company or by
                    any such Debentureholder, or

                    (3)    the Trustee shall become incapable of acting, or
                    shall be adjudged a bankrupt or insolvent, or a receiver of
                    the Trustee or of its property shall be appointed, or any
                    public officer shall take charge or control of the Trustee
                    or of its property or affairs for the purpose of
                    rehabilitation, conservation or liquidation,

             then, in any such case, the Company may remove the Trustee and
             appoint a successor trustee by written instrument, in duplicate,
             executed by order of the Board of Directors of the Company, one
             copy of which instrument shall be delivered to the Trustee so
             removed and one copy to the successor trustee, or, subject to the
             provisions of Section 8.09, any Debentureholder who has been a
             bona fide





                                       65
<PAGE>   73
             holder of a Debenture or Debentures for at least six months may,
             on behalf of himself and all others similarly situated, petition
             any court of competent jurisdiction for the removal of the Trustee
             and the appointment of a successor trustee.  Such court may
             thereupon after such notice, if any, as it may deem proper and
             prescribe, remove the Trustee and appoint a successor trustee.

             (c)    The holders of a majority in aggregate principal amount of
             the Debentures at the time outstanding may at any time remove the
             Trustee and nominate a successor trustee which shall be deemed
             appointed as successor trustee unless within ten days after such
             nomination the Company shall object thereto, in which case the
             Trustee so removed or any Debentureholder, upon the terms and
             conditions and otherwise as in subdivision (a) of this Section
             9.10 provided, may petition any court of competent jurisdiction
             for an appointment of a successor trustee.

             (d)    No resignation or removal of the Trustee and appointment of
             a successor trustee pursuant to any of the provisions of this
             Section 9.10 shall be effective until acceptance of appointment by
             the successor trustee as provided in Section 9.11.

             SECTION 9.11.  Acceptance by Successor Trustee.  Any successor
trustee appointed as provided in Section 9.10 shall execute, acknowledge and
deliver to the Company and to its predecessor trustee an instrument accepting
such appointment hereunder, and thereupon the resignation or removal of the
predecessor trustee shall become effective and such successor trustee, without
any further act, deed or conveyance, shall become vested with all the rights,
powers, duties and obligations of its predecessor hereunder, with like effect
as if originally named as trustee herein; but, nevertheless, on the written
request of the Company or of the successor trustee, the trustee ceasing to act
shall, upon payment of any amounts then due it pursuant to the provisions of
Section 9.06, execute and deliver an instrument transferring to such successor
trustee all the rights and powers of the trustee so ceasing to act.  Upon
request of any such successor trustee, the Company shall execute any and all
instruments in writing for more fully and certainly vesting in and confirming
to such successor trustee all such rights and powers.  Any trustee ceasing to
act shall, nevertheless, retain a lien upon all property or funds held or
collected by such trustee to secure any amounts then due it pursuant to the
provisions of Section 9.06.

             No successor trustee shall accept appointment as provided in this
Section 9.11 unless at the time of such acceptance such





                                       66
<PAGE>   74
successor trustee shall be qualified under the provisions of Section 9.08 and
eligible under the provisions of Section 9.09.

             Upon acceptance of appointment by a successor trustee as provided
in this Section 9.11, the Company shall mail notice of the succession of such
trustee hereunder to the holders of Debentures at their addresses as they shall
appear on the registry books of the Company.  If the Company fails to mail such
notice within ten days after acceptance of appointment by the successor
trustee, the successor trustee shall cause such notice to be mailed at the
expense of the Company.

             SECTION 9.12.  Succession by Merger and Certain Other Events.  Any
corporation into which the Trustee may be merged or converted or with which it
may be consolidated, or any corporation resulting from any merger, conversion
or consolidation to which the Trustee shall be a party, or any corporation
succeeding to the business of the Trustee, shall be the successor of the
Trustee hereunder without the execution or filing of any paper or any further
act on the part of any of the parties hereto.

             In case at the time such successor to the Trustee shall succeed to
the trusts created by this Indenture any of the Debentures shall have been
authenticated but not delivered, any such successor to the Trustee may adopt
the certificate of authentication of any predecessor trustee and deliver such
Debentures so authenticated; and in case at that time any of the Debentures
shall not have been authenticated, any successor to the Trustee may
authenticate such Debentures either in the name of any predecessor trustee
hereunder or in the name of such successor to the Trustee; and in all such
cases such certificates shall have the full force which it is anywhere in the
Debentures or in this Indenture provided that the certificate of the Trustee
shall have; provided, however, that the right to adopt the certificate of
authentication of any predecessor trustee or authenticate Debentures in the
name of any predecessor trustee shall apply only to its successor or successors
by merger, conversion or consolidation.

             SECTION 9.13. Limitation on Rights of Trustee as a Creditor.

             (a)    Subject to the provisions of subsection (b) of this Section
             9.13, if the Trustee shall be or shall become a creditor, directly
             or indirectly, secured or unsecured, of the Company or of any
             other obligor on the Debentures within four months prior to a
             default, as defined in subsection (c) of this Section 9.13, or
             subsequent to such a default, then, unless and until such default
             shall be cured, the Trustee shall set apart and hold in a special
             account for the benefit of the Trustee individually, the





                                       67
<PAGE>   75
             holders of the Debentures, and the holders of other indenture
             securities (as defined in subsection (c) of this Section 9.13):

                    (1)    an amount equal to any and all reductions in the
                    amount due and owing upon any claim as such creditor in
                    respect of principal or interest, effected after the
                    beginning of such four months' period and valid as against
                    the Company and its other creditors, except any such
                    reduction resulting from the receipt or disposition of any
                    property described in paragraph (2) of this subsection, or
                    from the exercise of any right of set-off which the Trustee
                    could have exercised if a petition in bankruptcy had been
                    filed by or against the Company upon the date of such
                    default; and

                    (2)    all property received by the Trustee in respect of
                    any claim as such creditor, either as security therefor, or
                    in satisfaction or composition therefor, or otherwise,
                    after the beginning of such four months' period, or an
                    amount equal to the proceeds of any such property, if
                    disposed of, subject, however, to the rights, if any, of
                    the Company and its other creditors in such property or
                    such proceeds.

             Nothing herein contained, however, shall affect the right of the
             Trustee:

                    (A)    to retain for its own account (i) payments made on
                    account of any such claim by any person (other than the
                    Company) who is liable thereon, and (ii) the proceeds of
                    the bona fide sale of any such claim by the Trustee to a
                    third person, and (iii) distributions made in cash,
                    securities or other property in respect of claims filed
                    against the Company in bankruptcy or receivership or in
                    proceedings for reorganization pursuant to the federal
                    bankruptcy laws, as now or hereafter constituted, or other
                    applicable federal or state law;

                    (B)    to realize, for its own account, upon any property
                    held by it as security for any such claim if such property
                    was so held prior to the beginning of such four months'
                    period;

                    (C)    to realize, for its own account, but only to the
                    extent of the claim hereinafter mentioned, upon any
                    property held by it as security for any such claim, if such
                    claim was created after the beginning of such four months'
                    period and such property was received as security therefor
                    simultaneously with the creation





                                       68
<PAGE>   76
                    thereof, and if the Trustee shall sustain the burden of
                    proving that at the time such property was so received the
                    Trustee had no reasonable cause to believe that a default,
                    as defined in subsection (c) of this Section 9.13, would
                    occur within four months; or

                    (D)    to receive payment on any claim referred to in
                    paragraph (B) or (C), against the release of any property
                    held as security for such claim as provided in such
                    paragraph (B) or (C), as the case may be, to the extent of
                    the fair value of such property.

             For the purposes of paragraphs (B), (C), and (D), property
substituted after the beginning of such four months' period for property held
as security at the time of such substitution shall, to the extent of the fair
value of the property released, have the same status as the property released,
and, to the extent that any claim referred to in any of such paragraphs is
created in renewal of or in substitution for or for the purpose of repaying or
refunding any pre-existing claim of the Trustee as such creditor, such claim
shall have the same status as such pre-existing claim.

             If the Trustee shall be required hereunder to maintain a special
account, the funds and property held in such special account and the proceeds
thereof shall be apportioned between the Trustee, the Debentureholders and the
holders of other indenture securities in such manner that the Trustee, the
Debentureholders and the holders of other indenture securities realize, as a
result of payments from such special account and payments of dividends on
claims filed against the Company in bankruptcy or receivership or in
proceedings for reorganization pursuant to the federal bankruptcy laws, as now
or hereafter constituted, or other applicable federal or state law, the same
percentage of their respective claims, figured before crediting to the claim of
the Trustee anything on account of the receipt by it from the Company of the
funds and property in such special account and before crediting to the
respective claims of the Trustee, the Debentureholders and the holders of other
indenture securities dividends on claims filed against the Company in
bankruptcy or receivership or in proceedings for reorganization pursuant to the
federal bankruptcy laws, as now or hereafter constituted, or other applicable
federal or state law, but after crediting thereon receipts on account of the
indebtedness represented by their respective claims from all sources other than
from such dividends and from the funds and property so held in such special
account.  As used in this paragraph, with respect to any claim, the term
"dividends" shall include any distribution with respect to such claim, in
bankruptcy or receivership or in proceedings for reorganization pursuant to the
federal bankruptcy laws, as now or hereafter constituted; or other applicable
federal or state law,





                                       69
<PAGE>   77
whether such distribution is made in cash, securities, or other property, but
shall not include any such distribution with respect to the secured portion, if
any, of such claim.  The court in which such bankruptcy, receivership, or
proceeding for reorganization is pending shall have jurisdiction (i) to
apportion between the Trustee, the Debentureholders, and the holders of other
indenture securities, in accordance with the provisions of this paragraph, the
funds and property held in such special account and the proceeds thereof, or
(ii) in lieu of such apportionment, in whole or in part, to give to the
provisions of this paragraph due consideration in determining the fairness of
the distributions to be made to the Trustee, the Debentureholders and the
holders of other indenture securities with respect to their respective claims,
in which event it shall not be necessary to liquidate or to appraise the value
of any securities or other property held in such special account or as security
for any claim, or to make a specific allocation of such distributions as
between the secured and unsecured portions of such claims, or otherwise to
apply the provisions of this paragraph as a mathematical formula.

             Any trustee who has resigned or been removed after the beginning
of such four months' period shall be subject to the provisions of this
subsection (a) as though such resignation or removal had not occurred.  If any
Trustee has resigned or been removed prior to the beginning of such four
months' period, it shall be subject to the provisions of this subsection (a) if
and only if the following conditions exist:

                    (i)    the receipt of property or reduction of claim which
                    would have given rise to the obligation to account, if such
                    Trustee had continued as trustee, occurred after the
                    beginning of such four months' period; and

                    (ii) such receipt of property or reduction of claim
                    occurred within four months after such resignation or
                    removal.

             (b)    There shall be excluded from the operation of subsection
             (a) of this Section 9.13 a creditor relationship arising from:

                    (1)    The ownership or acquisition of securities issued
                    under any indenture, or any security or securities having a
                    maturity of one year or more at the time of acquisition by
                    the Trustee;

                    (2)    advances authorized by a receivership or bankruptcy
                    court of competent jurisdiction, or by this Indenture, for
                    the purpose of preserving any property which shall at any
                    time be subject to the lien of this





                                       70
<PAGE>   78
                    Indenture or of discharging tax liens or other prior liens
                    or encumbrances thereon, if notice of such advance and of
                    the circumstances surrounding the making thereof is given
                    to the Debentureholders at the time and in the manner
                    provided in Section 7.04 with respect to reports pursuant
                    to subsections (a) and (b) thereof, respectively;

                    (3)    disbursements made in the ordinary course of
                    business in the capacity of trustee under an indenture,
                    transfer agent, registrar, custodian, paying agent, fiscal
                    agent or depositary, or other similar capacity;

                    (4)    an indebtedness created as a result of services
                    rendered or premises rented; or an indebtedness created as
                    a result of goods or securities sold in a cash transaction
                    as defined in subsection (c) of this Section 9.13;

                    (5)    the ownership of stock or of other securities of a
                    corporation organized under the provisions of Section 25(a)
                    of the Federal Reserve Act, as amended, which is directly
                    or indirectly a creditor of the Company; or

                    (6)    the acquisition, ownership, acceptance or
                    negotiation of any drafts, bills of exchange, acceptances
                    or obligations which fall within the classification of
                    self-liquidating paper as defined in subsection (c) of this
                    Section 9.13.

             (c)    As used in this Section 9.13:

                    (1)    The term "default" shall mean any failure to make
                    payment in full of the principal of or interest upon any of
                    the Debentures or upon the other indenture securities when
                    and as such principal or interest becomes due and payable;


                    (2)    The term "other indenture securities" shall mean
                    securities upon which the Company is an obligor (as defined
                    in the Trust Indenture Act of 1939) outstanding under any
                    other indenture (A) under which the Trustee is also
                    trustee, (B) which contains provisions substantially
                    similar to the provisions of subsection (a) of this Section
                    9.13, and (C) under which a default exists at the time of

                    purpose of financing the purchase, processing, manufacture,
                    shipment, storage or sale of goods, wares or merchandise
                    and which is secured by documents evidencing title to,
                    possession of, or a lien upon, the goods, wares or
                    merchandise or the receivables or proceeds arising from the
                    sale of goods, wares or merchandise previously constituting
                    the security, provided the security is received by the
                    Trustee simultaneously with the creation of the creditor
                    relationship with the Company arising from the making,
                    drawing, negotiating or incurring of the draft, bill of
                    exchange, acceptance or obligation; and


                    (5)    The term "Company" shall mean any obligor upon the 
                    Debentures.


             SECTION 9.14. Records of Trustee.   The Trustee shall retain in
its possession so long as any of the Debentures shall remain outstanding all
financial statements furnished to it pursuant to this Indenture.  The Trustee
shall at all times have access to those books and records of the Company which
may be reasonably required by the Trustee to fulfill its duties and obligations
hereunder, except that no such access shall be allowed to any books or records
constituting restricted security information under any law or governmental
regulation at the time applicable thereto.

                                  ARTICLE TEN

                        CONCERNING THE DEBENTUREHOLDERS

             SECTION 10.01.       Action by Debentureholders. Whenever in this
Indenture it is provided that the holders of a specified percentage in
aggregate principal amount of the Debentures may take any action (including the
making of any demand or request, the giving of any notice, consent or waiver or
the taking of any other action) the fact that at the time of taking any such
action the holders of such specified percentage have joined therein may





                                       72
<PAGE>   80
be evidenced (a) by any instrument or any number of instruments of similar
tenor executed by Debentureholders in person or by agent or proxy appointed in
writing, or (b) by the record of the holders of Debentures voting in favor
thereof at any meeting of Debentureholders duly called and held in accordance
with the provisions of Article Eleven, or (c) by a combination of such
instrument or instruments and any such record of such a meeting of
Debentureholders.

             SECTION 10.02. Proof of Execution by Debentureholders; Evidence of
Holdings.  Subject to the provisions of Section 9.01 and 11.05, proof of the
fact and date of execution of any instrument by a Debentureholder or his agent
or proxy and proof of the holding by any person of any of the Debentures shall
be sufficient for any purpose of this Indenture and conclusive in favor of the
Trustee and the Company if made in the following manner:

             (a)    The fact and date of the execution by any such person of
             any instrument may be proved by the certificate of any notary
             public or other officer of any jurisdiction authorized to take
             acknowledgments of deeds or administer oaths that the person
             executing such instrument acknowledged to him the execution
             thereof, or by an affidavit of a witness to such execution sworn
             to before any such notary or other such officer and where such
             execution is by an officer of a corporation or association or a
             member of a partnership, on behalf of such corporation,
             association or partnership, such certificate or affidavit shall
             also constitute sufficient proof of his authority.

             (b)    The ownership of Debentures shall be proved by the
             registers of such Debentures or by a certificate of the registrar
             thereof.

             The record of any Debentureholders' meeting shall be proved in the
manner provided in Section 11.06.  The Trustee may require such additional
proof of any matter referred to in this Section 10.02 as it shall deem
necessary.


             SECTION 10.03.  Who Deemed Absolute Owners.   The Company, the
Trustee, any paying agent, any conversion agent and any Debenture registrar may
deem and treat the person in whose name any Debenture shall be registered upon
the books of the Company as the absolute owner of such Debenture (whether or
not such Debenture shall be overdue and notwithstanding any notation of
ownership or writing thereon by anyone other than the Company or any Debenture
registrar) for the purpose of receiving payment of or on account of the
principal of and interest on such Debenture





                                       73
<PAGE>   81
and for all other purposes; and neither the Company nor the Trustee nor any
paying agent nor any conversion agent nor any Debenture registrar shall be
affected by any notice to the contrary.  Payment of or on account of the
principal of and (subject to the provisions of Section 2.03) interest on such
Debenture shall be made only to or upon the order in writing of the registered
holder thereof.  All such payments and all such conversions shall be valid,
and, to the extent of the sum or sums so paid, effectual to satisfy and
discharge the liability for monies payable upon any such Debenture.


             SECTION 10.04.  Company-owned Debentures Disregarded.   In
determining whether the holders of the requisite aggregate principal amount of
Debentures have concurred in any direction or consent under this Indenture,
Debentures which are owned by the Company or any other obligor on the
Debentures or by any person directly or indirectly controlling or controlled by
or under direct or indirect common control with the Company or any other
obligor on the Debentures shall be disregarded and deemed not to be outstanding
for the purpose of any such determination; provided that for the purposes of
determining whether the Trustee shall be protected in relying on any such
direction or consent only Debentures which the Trustee knows are so owned shall
be so disregarded.  The Company shall, immediately upon issuance of the
Debentures, provide the Trustee with an Officers' Certificate and an Opinion of
Counsel specifying which Debentures are so owned and that no other Debentures
are so owned.  The Company shall provide further Officers' Certificates and
Opinions of Counsel as necessary to reflect changes in such information.
Debentures so owned which have been pledged in good faith may be regarded as
outstanding for the purposes of this Section 10.04, if the pledgee shall
establish to the satisfaction of the Trustee the pledgee's right to vote such
Debentures and that the pledgee is not a person directly or indirectly
controlling or controlled by or under direct or indirect common control with
the Company or any such other obligor.  In case of a dispute as to such right,
any decision by the Trustee taken upon the advice of counsel shall be full
protection to the Trustee.

             SECTION 10.05.  Revocation of Consents; Future Holders Bound.   At
any time prior to (but not after) the evidencing to the Trustee, as provided in
Section 10.01, of the taking of any action by the holders of the percentage in
aggregate principal amount of the Debentures specified in this Indenture in
connection with such action, any holder of a Debenture which is included in the
Debentures the holders of which have consented to such action may, by filing
written notice with the Trustee at its office and upon proof of holding as
provided in Section 10.02, revoke such action so far as concerns such holder's
Debenture.  Absent a proper revocation, any consent to an action given by the
holder of





                                       74
<PAGE>   82
any Debenture shall be conclusive and binding upon such holder and upon all
future holders and owners of such Debenture, irrespective of whether or not any
notation in regard thereto is made upon such Debenture or any Debenture issued
in exchange or substitution therefor.  Any action taken by the holders of the
percentage in aggregate principal amount of the Debentures specified in this
Indenture in connection with such action shall be conclusively binding upon the
Company, the Trustee and the holders of all the Debentures.


             SECTION 10.06.        Transfer of Debentures.   Except as provided
herein, the Debentures may not be sold, assigned, transferred, pledged or
otherwise hypothecated.  A Debentureholder may pledge or hypothecate a
Debenture for the purpose of borrowing money to buy the Debenture provided that
the Company consents in writing to such intended pledge or hypothecation prior
to consummation of such pledge or hypothecation.  Any such consent shall be
substantially in the form attached hereto as Exhibit A.  Upon giving such
consent, the Company shall furnish to the Trustee and any conversion agent an
Officers' Certificate which shall identify the Debentures covered by such
consent by stating the serial number, name of registered holder and principal
amount of such Debentures.  The duly authorized representative of the estate of
a deceased Debentureholder may request that a Debenture held in that estate be
registered in the name of the person or persons to whom such Debenture passed
by will or the laws of intestate succession, provided that such representative
shall have supplied proof satisfactory to the Company and the Trustee of his
authority, and of any other matters which the Trustee or the Company may deem
relevant.  A person who has foreclosed on a pledge or hypothecation on a
Debenture made in compliance with this Section 10.06 may request that such
Debenture be registered in the name of such person.  As used herein, the term
"person" shall include any corporation, bank, savings and loan association,
partnership and similar business entities.


                                 ARTICLE ELEVEN

                           DEBENTUREHOLDERS' MEETINGS

                    or to give any directions to the Trustee, or to consent to
                    the waiving of any default hereunder and its consequences,
                    or to take any other action

<PAGE>   83
                    authorized to be taken by Debentureholders pursuant to any

                    (2)    to remove the Trustee and nominate a successor
                    trustee pursuant to the provisions of Article Nine;

                    (3)    to consent to the execution of an indenture or
                    indentures supplemental hereto pursuant to the provisions
                    of Section 12.02; or

                    (4)    to take any other action authorized to be taken by
                    or on behalf of the holders of any specified aggregate
                    principal amount of the Debentures under any other
                    provision of this Indenture or under applicable law.

             SECTION 11.02.  Call of Meetings by Trustee.   The Trustee may at
any time call a meeting of Debentureholders to take any action specified in
Section 11.01, to be held at such time and at such place in the City of
Jackson, Mississippi, as the Trustee shall determine.  Notice of every meeting
of the Debentureholders, setting forth the time and the place of such meeting
and in general terms the action proposed to be taken at such meeting, shall be
mailed to the holders of Debentures at their addresses as they shall appear on
the registry books of the Company.  Such notice shall be mailed not less than
twenty nor more than one hundred and eighty days prior to the date fixed for
the meeting.

             SECTION 11.03.  Call of Meetings by Company or Debentureholders.
In case at any time the Company, pursuant to a resolution of its Board of
Directors, or the holders of at least ten per cent in aggregate principal
amount of the Debentures then outstanding, shall have requested the Trustee to
call a meeting of Debentureholders, by written request setting forth in
reasonable detail the action proposed to be taken at the meeting, and the
Trustee shall not have mailed the notice of such meeting within twenty days
after receipt of such request, then the Company or such Debentureholders may
determine the time and the place in the City of Jackson, Mississippi, for such
meeting and may call such meeting to take any action authorized in Section
11.01, by mailing notice thereof as provided in Section 11.02.

             SECTION 11.04.  Qualifications for Voting.   To be entitled to
vote at any meeting of Debentureholders a person shall (a) be a holder of one
or more Debentures; or (b) be a person appointed by an instrument in writing as
proxy by a holder of one or more Debentures.  The only persons who shall be
entitled to be present or to speak at any meeting of Debentureholders shall be

Company and its counsel.





                                       76
<PAGE>   84
             SECTION 11.05.  Regulations.   Notwithstanding any other
provisions of this Indenture, the Trustee may make such reasonable regulations
as it may deem advisable for any meeting of Debentureholders, in regard to
proof of the holding of Debentures and of the appointment of proxies, and in
regard to the appointment and duties of inspectors of votes, the submission and
examination of proxies and other evidence of the right to vote, and such other
matters concerning the conduct of the meetings as it shall think fit.

             The Trustee shall, by an instrument in writing, appoint a
temporary chairman of the meeting, unless the meeting shall have been called by
the Company or by Debentureholders as provided in Section 11.03, in which case
the Company or the Debentureholders calling the meeting, as the case may be,
shall in like manner appoint a temporary chairman.  A permanent chairman and a
permanent secretary of the meeting shall be elected by majority vote of the
meeting.

             Subject to the provisions of Section 10.04, at any meeting each
Debentureholder or proxy shall be entitled to one vote (and/or fraction
thereof) for each $50.00 principal amount of Debentures (and/or fraction
thereof) held or represented by him; provided, however, that no vote shall be
cast or counted at any meeting in respect of any Debenture challenged as not
outstanding and ruled by the chairman of the meeting to be not outstanding.
The chairman of the meeting shall have no right to vote other than by virtue of
Debentures held by him or instruments in writing as aforesaid duly designating
him as the person to vote on behalf of other Debentureholders.

             At any meeting of Debentureholders, the presence of persons
holding or representing Debentures in an aggregate principal amount sufficient
under the appropriate provisions of this Indenture to take action upon the
business for the transaction of which such meeting was called shall constitute
a quorum.  Any meeting of Debentureholders duly called pursuant to the
provisions of Section 11.02 or 11.03 may be adjourned from time to time by vote
of the holders (or proxies for the holders) of a majority of Debentures
represented at the meeting and entitled to vote, whether or not constituting a
quorum, and the meeting may be held as so adjourned without further notice.

             SECTION 11.06.  Voting.   The vote upon any resolution submitted
to any meeting of Debentureholders shall be by written ballots on which shall
be subscribed the signatures of the holders of Debentures or of their
representatives by proxy and the serial number or numbers of the Debentures
held or represented by them.  The permanent chairman of the meeting shall
appoint two inspectors of votes who shall count all votes cast at the meeting
for or against any resolution and who shall make and file with the





                                       77
<PAGE>   85
secretary of the meeting their verified written reports in duplicate for all
votes cast at the meeting.  A record in duplicate of the proceedings of each
meeting of Debentureholders shall be prepared by the secretary of the meeting
and there shall be attached to said record the original reports of the
inspectors of votes on any vote by ballot taken thereat and affidavits by one
or more persons having knowledge of the facts setting forth a copy of the
notice of the meeting and showing that said notice was mailed as provided in
Section 11.02.  The record shall be signed and verified by the affidavits of
the permanent chairman and secretary of the meeting, and one of the duplicates
shall be delivered to the Company and the other to the Trustee to be preserved
by the Trustee.

             Any record so signed and verified shall be conclusive evidence of
the matters therein stated.

             SECTION 11.07.  No Delay of Rights by Meeting.   Nothing in this
Article Eleven contained shall be deemed or construed to authorize or permit,
by reason of any call of a meeting of Debentureholders or any rights expressly
or impliedly conferred hereunder to make such call, any hindrance or delay in
the exercise of any right or rights conferred upon or reserved to the Trustee
or to the Debentureholders under any of the provisions of this Indenture or of
the Debentures.


                                 ARTICLE TWELVE

                            SUPPLEMENTAL INDENTURES

             SECTION 12.01.  Supplemental Indentures without Consent of
Debentureholders.   The Company, when authorized by resolution of its Board of
Directors, and the Trustee may from time to time and at any time enter into an
indenture or indentures supplemental hereto for one or more of the following
purposes:

             (a)    to make provision with respect to the conversion rights of
             holders of Debentures pursuant to the requirements of Section
             5.09;

             (b)    to evidence the succession of another corporation to the
             Company, or successive successions, and the assumption by the
             successor corporation of the covenants, agreements and obligations
             of the Company pursuant to Article Thirteen hereof;

             (c)    to add to the covenants of the Company such further
             covenants, restrictions or conditions for the protection of the
             holders of the Debentures as the Board of Directors of the Company
             and the Trustee shall consider to be for





                                       78
<PAGE>   86
             the protection of the holders of Debentures, and to make the
             occurrence, or the occurrence and continuance, of a default in any
             of such additional covenants, restrictions or conditions a default
             or an Event of Default permitting the enforcement of all or any of
             the several remedies provided in this Indenture as herein set
             forth; provided, however, that in respect of any such additional
             covenant, restriction or condition such supplemental indenture may
             provide for a particular period of grace after default (which
             period may be shorter or longer than that allowed in the case of
             other defaults) or may provide for an immediate enforcement upon
             such default or may limit the remedies available to the Trustee
             upon such default;

             (d)    to provide for the issuance under this Indenture of
             Debentures in coupon form (including Debentures registrable as to
             principal only), but otherwise with all the provisions and subject
             to all the conditions and limitations of the Debentures issued
             hereunder in fully registered form, and to provide for
             exchangeability of such Debentures with the Debentures issued
             hereunder in fully registered form; and

             (e)    to cure any ambiguity or to correct or supplement any
             provision contained herein or in any supplemental indenture which
             may be defective or inconsistent with any other provision
             contained herein or in any supplemental indenture, or to make such
             other provisions in regard to matters or questions arising under
             this Indenture which shall not be inconsistent with the provisions
             of this Indenture, provided such action pursuant to this clause
             (e) shall not adversely affect the interests of the holders of the
             Debentures.

             (f)    to modify, eliminate, or add to the provisions of this
             Indenture to such extent as may be necessary to effect the
             qualification of this Indenture under the Trust Indenture Act, or
             under any similar federal statute hereafter enacted, if such
             qualification is or becomes necessary or desirable, and to add to
             this Indenture such other provisions as may be expressly permitted
             by the Trust Indenture Act, excluding, however, the provisions
             referred to in Section 316(a)(2) of the Trust Indenture Act as in
             effect at the date as of which this instrument was executed, or
             any corresponding provision in any similar federal statute
             hereafter enacted.

             The Trustee is hereby authorized to join with the Company in the
execution of any such supplemental indenture, to make any further appropriate
agreements and stipulations which may be therein contained and to accept the
conveyance, transfer and





                                       79
<PAGE>   87
assignment of any property thereunder, but the Trustee shall not be obligated
to enter into any such supplemental indenture which affects the Trustee's own
rights, duties or immunities under this Indenture or otherwise.

             Any supplemental indenture authorized by the provisions of this
Section 12.01 may be executed by the Company and the Trustee without the
consent of the holders of any of the Debentures at the time outstanding,
notwithstanding any of the provisions of Section 12.02.

             SECTION 12.02.  Supplemental Indentures with Consent of
Debentureholders.   With the consent (evidenced as provided in Section 10.01)
of the holders of not less than sixty-six and two-thirds per cent in aggregate
principal amount of the Debentures at the time outstanding, the Company, when
authorized by resolution of its Board of Directors, and the Trustee may from
time to time and at any time enter into an indenture or indentures supplemental
hereto for the purpose of adding any provisions to or changing in any manner or
eliminating any of the provisions of this Indenture or of any supplemental
indenture or of modifying in any manner the rights of the holders of the
Debentures; provided, however, that no such supplemental indenture shall (i)
extend the fixed maturity of any Debentures, or reduce the rate or extend the
time of payment of interest thereon, or reduce the principal amount thereof, or
change any place of payment where, or the coin or currency in which, any
Debenture or the interest thereon, is payable, or modify the provisions of this
Indenture with respect to the subordination of the Debentures in a manner
adverse to the Debentureholders, or impair the right to convert the Debentures
into 1994-1 Series Stock on the terms set forth herein (except as permitted by
Section 12.01(a)), without the consent of the holder of each Debenture so
affected, or (ii) reduce the aforesaid percentage of Debentures, the holders of
which are required to consent to any such supplemental indenture, without the
consent of the holders of all Debentures then outstanding.

             Upon the request of the Company, accompanied by a copy of the
resolutions of its Board of Directors certified by its Secretary or Assistant
Secretary authorizing the execution of any such supplemental indenture, and
upon the filing with the Trustee of evidence of the consent of Debentureholders
as aforesaid, the Trustee shall join with the Company in the execution of such
supplemental indenture unless such supplemental indenture affects the Trustee's
own rights, duties or immunities under this Indenture or otherwise, in which
case the Trustee may in its discretion, but shall not be obligated to, enter
into such supplemental indenture.

             Promptly after the execution by the Company and the Trustee of any
supplemental indenture pursuant to this Section





                                       80
<PAGE>   88
12.02, the Company, at its cost and expense, shall mail a notice, setting forth
in general terms the substance of such supplemental indenture, to all
Debentureholders of record as of the date of such supplemental indenture.


             It shall not be necessary for the consent of the Debentureholders
under this Section 12.02 to approve the particular form of any proposed
supplemental indenture, but it shall be sufficient if such consent shall
approve the substance thereof.


             SECTION 12.03.  Compliance with Trust Indenture Act; Effect of
Supplemental Indentures.   Any supplemental indenture executed pursuant to the
provisions of this Article Twelve shall comply with the Trust Indenture Act of
1939 as in effect on the date of execution thereof if such compliance is
necessary or is determined by the Company to be desirable.  Upon the execution
of any supplemental indenture pursuant to the provisions of this Article
Twelve, this Indenture shall be and be deemed to be modified and amended in
accordance therewith and the respective rights, limitation of rights,
obligations, duties and immunities under this Indenture of the Trustee, the
Company and the holders of Debentures shall thereafter be determined, exercised
and enforced hereunder subject in all respects to such modifications and
amendments, and all the terms and conditions of any such supplemental indenture

for any and all purposes.


             SECTION 12.04.  Notation on Debentures.   Debentures authenticated
and delivered after the execution of any supplemental indenture pursuant to the
provisions of this Article Twelve may bear a notation in form approved by the

Company or the Trustee shall so determine, new Debentures so modified as to
conform, in the opinion of the Trustee and the Board of Directors of the
Company, to any modifications of this Indenture contained in any such
supplemental indenture may be prepared and executed by the Company,
authenticated by the Trustee and delivered in exchange for the Debentures then
outstanding.


             SECTION 12.05.  Evidence of Compliance of Supplemental Indenture
to be Furnished Trustee.   The Trustee, subject to the provisions of Sections

                                ARTICLE THIRTEEN

                 CONSOLIDATION, MERGER AND SALE BY THE COMPANY

             SECTION 13.01.  Consolidation, Merger or Sale of Assets Permitted.
The Company covenants that it will not merge or consolidate with any other
corporation or sell or convey all or substantially all of its assets to any
person, firm or corporation, (i) unless either (a) the Company shall be the
continuing corporation, or (b) the successor (if other than the Company) shall
be a corporation which shall expressly assume the due and punctual payment of
the principal of and interest on all the Debentures, according to their tenor,
and the due and punctual performance and observance of all of the covenants and
conditions of this Indenture to be performed by the Company by supplemental
indenture satisfactory to the Trustee, executed and delivered to the Trustee by
such corporation, and (ii) unless the Company or such successor corporation, as
the case may be, shall not, immediately after such merger or consolidation, or
such sale or conveyance, be in default in the performance of any such covenant
or condition.

             SECTION 13.02.  Succession by Successor Corporation.  In case of
any such merger, consolidation, sale or conveyance and upon any such assumption
by the successor corporation, such successor corporation shall succeed to and
be substituted for the Company, with the same effect as if it had been named
herein as a party hereto instead of the Company.  Such successor corporation
thereupon may cause to be signed, and may issue either in its own name or in
the name of First Mississippi Corporation, any or all of the Debentures
issuable hereunder which theretofore shall not have been signed by the Company
and delivered to the Trustee; and, upon the order of such successor corporation
(instead of First Mississippi Corporation) and subject to all the terms,
conditions and limitations in this Indenture prescribed, the Trustee shall
authenticate and shall deliver any Debentures which previously shall have been
signed and delivered by the officers of the Company to the Trustee for
authentication, and any Debentures which such successor corporation thereafter
shall cause to be signed and delivered to the Trustee for that purpose.  All
the Debentures so issued shall in all respects have the same legal rank and
benefit under this Indenture as the Debentures theretofore or thereafter issued
in accordance with the terms of this Indenture as though all of such Debentures
had been issued at the date of the execution hereof.

             In case of any such consolidation, merger, sale or conveyance such
changes in phraseology and form (but not in substance) may be made in the
Debentures thereafter to be issued as may be appropriate.

<PAGE>   90
             SECTION 13.03.  Evidence to be Furnished Trustee.  The Trustee,
subject to the provisions of Sections 9.01 and 9.02, may receive an Officers'
Certificate and an Opinion of Counsel as conclusive evidence that any such
consolidation, merger, sale or conveyance and any such assumption comply with
the provisions of this Article Thirteen.

             SECTION 14.01.  Discharge of Indenture.  If (a) there shall have
been delivered to the Trustee for cancellation all Debentures theretofore
authenticated (other than any Debentures which shall have been destroyed, lost
or stolen and in lieu of or in substitution for which other Debentures shall
have been authenticated and delivered), or (b) all such Debentures not
theretofore delivered to the Trustee for cancellation shall have become due and
payable at maturity and the Company shall have deposited with the Trustee, in
trust, funds sufficient to pay at maturity all of such Debentures (other than
any Debentures which shall have been destroyed, lost or stolen and in lieu of
or in substitution for which other Debentures shall have been authenticated and
delivered) not theretofore delivered to the Trustee for cancellation, including
principal and interest, and such deposit shall be upon terms making such funds
payable forthwith upon due presentation, whether before or after such date of
maturity or redemption of such Debentures, and if in either case the Company
shall also pay or cause to be paid all other sums payable hereunder by the
Company, and shall deliver to the Trustee an Officers' Certificate and an
Opinion of Counsel each stating that all conditions precedent herein provided
for relating to the satisfaction and discharge of this Indenture have been
complied with, then (except as to any remaining rights of conversion of the
Debentures) this Indenture shall cease to be of further effect, and the
Trustee, on demand of the Company accompanied by an Officers' Certificate and
an Opinion of Counsel as required by Section 16.06 and at the cost and expense
of the Company, shall execute power instruments acknowledging satisfaction of
and discharging this Indenture.  However, this Indenture shall continue in
effect to the extent necessary to provide for (a) the conversion of Debentures
as provided in Article Five, (b) the discharge of the duties and obligations of
the Trustee, and (c) the right of the holders of the Debentures to payment of
funds held by the Trustee pursuant to this Article Fourteen.  The Company,
however, hereby agrees to compensate and reimburse the Trustee for any services
rendered and costs or expenses thereafter reasonably and properly incurred by
the Trustee in connection with





                                       83

harmless against any loss, liability, or expense as provided in Section 9.06
hereof.


             SECTION 14.02.  Deposited Monies to be Held in Trust by Trustee.
All monies deposited with the Trustee pursuant to Section 14.01 shall be held
in trust and, subject to the provisions of this Indenture and the Debentures,
applied by it to the payment, either directly or through any paying agent, to
the holders of the particular Debentures for the payment of which such monies
have been deposited with the Trustee, of all sums due thereon for principal and
interest.


             SECTION 14.03.  Paying Agent to Repay Monies Held.  Upon the
satisfaction and discharge of this Indenture, all monies then held by any
paying agent of the Debentures (other than the Trustee) shall, upon demand of
the Company, be repaid to it or paid to the Trustee, and thereupon such paying
agent shall be released from all further liability with respect to such monies.


             SECTION 14.04.  Unclaimed Monies.  Any monies deposited with the
Trustee or any paying agent (including monies held in trust by the Company if
it shall act as its own paying agent) not applied but remaining unclaimed by
the holders of Debentures for six years after the date upon which the principal
of or interest on such Debentures shall have become due and payable shall be
repaid to the Company by the Trustee or such paying agent on demand, or if held
in trust by the Company may at the Company's option be released from such
trust; and the holder of any of the Debentures entitled to receive such payment
shall thereafter look only to the Company, as the holder of a general claim,
for the payment thereof, and all liability of the Trustee or such paying agent
with respect to such monies, and all liability of the Company as Trustee
thereof, shall thereupon cease, provided, however, that the Trustee or such
paying agent, before being required to make any such repayment, may at the
expense of the Company cause to be published once a week for two successive
weeks (in each case on any day of the week) in an Authorized Newspaper a notice
that said monies have not been so applied and that after a date named therein
any unclaimed balance of said monies then remaining will be returned to the
Company.

any Debentures, or for any claim based thereon or otherwise in respect thereof,
and no recourse under or upon any obligation, covenant or agreement of the
Company in this Indenture, or in any Debenture, or because of the creation of
any indebtedness represented thereby, shall be had against any incorporator,
stockholder, officer or director, as such, past, present or future, of the
Company or of any successor corporation, either directly or through the Company
or any successor corporation, whether by virtue of any constitution, statute or
rule of law, or by the enforcement of any assessment or penalty or otherwise;

                                       86
<PAGE>   94
authorized by law to remain closed, then such payment or conversion, as the

Others.  In case any one or more of the provisions contained in this Indenture
or in the Debentures shall for any reason be held to be invalid, illegal or
unenforceable in any respect, such invalidity, illegality or unenforceability
shall not affect any other provisions of this Indenture or of such Debentures,
but this Indenture and such Debentures shall be construed as if such invalid or
illegal or unenforceable provision had never been contained herein or therein.

[FIRST MISSISSIPPI CORPORATION LETTERHEAD]


February 20, 1995



Board of Directors
FIRST MISSISSIPPI CORPORATION
700 North Street
Jackson, Mississippi  39202-3095

Gentlemen:

This opinion is given in connection with the Registration Statement on Form S-8
(the "Registration Statement") which FIRST MISSISSIPPI CORPORATION (the
"Company") is filing with the Securities and Exchange Commission to register
$21,312.50 in principal amount of its 1994-1 Series Convertible Subordinated
Debentures (the "1994-1 Series Debentures"), for sale to outside directors,
1,000 shares of its 1994-1 Series Convertible Preferred Stock (the "1994-1
Series Stock") issuable upon conversion of the 1994-1 Series Debentures, and
1,000 shares (subject to certain adjustments) of its Common Stock (the "Common
Stock") issuable upon conversion of the 1994-1 Series Stock, all pursuant to
the Company's 1988 Long-Term Incentive Plan (the "Plan").

As General Counsel of the Company, I am familiar with the Company's Articles of
Incorporation and By-Laws; the Plan; the Registration Statement; the actions
taken and resolutions passed by the Board of Directors relative to the 1994-1
Series Debentures and the 1994-1 Series Stock and the taking of certain other
actions in connection with the offering and sale of the 1994-1 Series
Debentures, the 1994-1 Series Stock and the Common Stock issuable pursuant to
the Plan; the Indenture, dated as of November 14, 1994, between the Company and
Deposit Guaranty National Bank, as Trustee, relating to the 1994-1 Series
Debentures; the form of 1994-1 Series Debentures; the Debenture Options, and
such other matters and documents deemed necessary for the purpose of rendering
this opinion.

On the basis of the foregoing, I am of the opinion that:

         (1)     the 1994-1 Series Debentures have been duly authorized and,
                 when issued and paid for in accordance with the terms of the
                 Plan, the Indenture and the Debenture Options, will be validly
                 issued and binding obligations of the Company;

         (2)     the shares of 1994-1 Series Stock issuable upon conversion of
                 the 1994-1 Series Debentures will, when so issued in
                 accordance with the Plan, the Indenture and the resolutions
                 passed by the Company's Board of Directors, be legally issued,
                 fully paid and non-assessable.

         (3)     the shares of Common Stock issuable upon conversion of the
                 1994-1 Series Stock, will, when so issued in accordance with
                 the Plan, the Indenture and the resolutions passed by the
                 Company's Board of Directors, be legally issued, fully paid
                 and non-assessable.

This opinion is subject to the following qualifications:

         (a)     Rights and remedies set forth in the Indenture and the 1994-1
                 Series Debentures are subject to applicable bankruptcy,
                 insolvency, moratorium, reorganization and other laws now or
                 hereafter in effect affecting the enforcement of creditors'
                 rights generally, and

         (b)     No opinion is expressed as to the availability of any remedy
                 or remedies that may be sought with respect to the specific
                 enforcement of any provision of the Indenture or the 1994-1
                 Series Debentures.

I hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to me and to my opinion in the
Registration Statement.

Very truly yours,
